92 reviews for GR48B 4′ x 8′ Overhead Garage Storage Rack Black

1st, about me. I’m a simple highschool diploma recipient and an “uneducated” jar head grunt. This needs to be said to emphasize the ease of this installation. Not to insult anyone who had trouble, but maybe you shouldn’t be installing anything. Ever.

Instructions: I don’t know how good they are. I just looked at the picture on the front, counted the holes and hardware, did some simple math, and went at it. It’s really all that’s needed. Seriously.

Arrival condition: packed very well and all parts are separated accordingly. It’s easy to take inventory if counting is something you can do with little supervision. There were 0 defects that would effect the integrity of the structure. I didn’t look for small scratches because I don’t care at all and neither do the boxes I’m storing.

Capacity: I filled it up with boxes full of average storable material such as clothing, decorations, blankets, 2 Christmas trees, and other random items you only need seasonally. It didn’t even blink any eye at it. 12 totes (2 being long tree totes) Access is simple if you have a ladder and decent balance (which you clearly need in addition to standard tools for installation)

Tools and skills required: ladder of appropriate height, drill, tape measure, 3/16″ drill bit, pencil, and wrenches provided if you don’t have any. I used a 13mm socket on my impact driver and a 13mm wrench to secure the lock nuts. This is not necessary, but simplified it greatly. If you can measure, count, turn your fingers, and use a drill, you’re all set.

Suggestions: If you can’t move the box it came in alone, don’t install it alone. It’s 68lbs. Put 2 racks together at a time and install them to the braces. Don’t do something ridiculous like try to lift and hold the 4’x8′ metal cage above your head while on a ladder. If this crossed your mind, put your tools down and ask for help. You probably need it. If you do 2 racks at a time you can easily do it by yourself.

Time: 1st, who cares. It will last probably as long as your house so just put in the work. If you’re in a hurry and don’t have time, pay someone to do it for you. If you do care, it took me just a little over 2 hours from moving the box from the porch to finishing this review.

I don’t get paid for reviews and left this one because I feel this product is outstanding and has been degraded by a few people who are just simply incapable of such work. We’re all made for different things and that’s ok. Just know who you are and what you’re made of before leaving poor reviews.

Enjoy and be safe!

First, when this thing arrived it took two of us to get the box into the garage (heavy). Everyone told me they were a real difficult install, so I put it off for a few months. Finally decided to bite the bullet and unboxed the unit and turned to YouTube for some install videos. The biggest challenge was getting the measurements on the ceiling right before starting. I have a hammer drill and used a socket to put the bolts into the rafters. That part was pretty easy. Putting together the down rods requires some time as there are a bazillion bolts and nuts. When the time came to put the bottom rack up, I made up some bungie cables to hold the rack up close to the down rods, which allowed me to take my time putting the bolts in without straining. It was a much easier job than I anticipated and I’m glad I didn’t wimp out. Got a pile of holiday decoration boxes off the floor and out of my way. Happy Camper here.

Found this product through a friend who installed in his garage. He had mentioned they are rather large and can’t be customized. They show an installation of 2ft x 4ft platforms running 4ft out from the wall into your garage space.

I bought them on Deal of The Day and found that I could, in fact, highly customize them to take up less space in your garage if you have a smaller space. I turned turned two long-ways and made a 8ft long by 2ft deep shelf. All of the platforms are made to turn and still attach in any arrangement you want to put them with some thinking ahead. Unfortunately you do not get enough supports to utilize everything if you install any other way than what’s pictured. I’m still trying to find a way to buy extra supports to use the remaining two shelves I have.

I had them up in 30-40 minutes and they seem solid enough to support the rated 600lbs.

I’ve recently installed this 4′ x 8′ overhead storage unit by Fleximounts, and I love it! I placed mine just over my oil storage tank, which was pretty much all wasted space. I found that some of my ceiling joists were not 24″ on center, but I was able to install the unit anyway. I’ve posted a YouTube video on the installation process (search for it). This unit is sturdy, easy to install, and it instantly maximizes previously unused space. The range of adjustment allows this unit to be quite functional at varying ceiling heights and storage needs. Accessing this storage space is far easier, and faster, than climbing up my pull down stair case and trying to maneuver around my unsafe garage attic space. I also like that I can hang things like extension cords and drop lights below the unit, further maximizing the space that was previously unused. I can see one or two more of these in my future for sure. If you’re constantly shuffling things around your garage,and always trying to find space, buy this overhead storage unit by Fleximounts today!

Stable and sturdy. The instructions were pretty clear.

Note that it’s a considerable effort to set it up. Works better if it’s 2 people. But, it’s totally worth it 🙂

Product as described, very easy to install.
Not only would I recommend this…but I think I will be buying at least one more, probably two, in the near future!!

I normally don’t write reviews for things but this was something I felt obligated because of how awesome this thing is. Got this on a cyber Monday deal for $115 which is a steal for this…I would say anything under $200 and it’s worth it. I’m going to go through a few points to make your life easier with this product.
1. Study the dimensions of this thing and make sure your particular installation can accommodate it. It is 8 x 4 and it must be installed perpendicular to the floor joists that way the load across 6 joists. I would not recommend installing this parallel to joists as then you are relying on only 3 joists for support.
2. Make sure you have 2 people for installing. Is it possible with 1, sure but it will save you SO much to have some help. My Dad came over and helped me out.
3. It accommodates heights between 22-40 inches. I had to cut down all 12 pieces to accommodate a 20 inch height. It is possible it’s just a chore but this is not a knock on the product.
4. If you do the 3 steps above you will have a successful installing and be extremely happy with the install as I am. It is VERY sturdy and adds storage space where it’s just empty space. Takes planning but this is just the nature of the product and not a knock or it at all. Comes with giant lag bolts, they give you a tool for this but I recommend at the minimum a ratchet. Some have said that the instructions could be better but honestly it’s pretty straight forward but it’s tough to install and will take you some time to install it properly.

These shelves hold tons of stuff, and fit perfectly in the garage, just above the garage door and cars in a normal sized garage. Make sure you measure and double check your measurements to ensure everything fits where you want! Now, I am a young, fit, and relatively handy male, and these were a beast to install. The first one took the better part of 4 hours, between measuring, re-measuring, drilling, screwing, assembling, lifting, and installing to get exactly right. The second was a bit faster because I practiced with the first, but still took at least a couple hours. Instructions are good and thorough, and nothing was necessarily difficult to do (except maybe trying to lift it up and secure it by yourself. Wouldn’t recommend that; almost hurt myself). All-in-all very satisfied with this product and how it’s helped me in my neverending quest to perfectly organize my garage!

I bought two kits – 8×4’ size. They are sturdy and appear well built. Great amount of storage space. I don’t know if they will support 600lbs, but I’m 260 and they supported me 😄. The instructions are clear BUT, locating the studs in the ceiling is tough, even with a stud finder. If you are able to easily and quickly locate them – installation will go quickly. Another challenge, measure the distance between your ceiling studs BEFORE you buy. I didn’t, assumed they would be the standard 16, 20 or 24 “ on center. Mine were NOT. This presents a problem as the ceiling supports in the kit are 25.5” long. This gave me very little “wiggle” room when mounting- but I made it work. Also, there are nylon lock nuts for the ceiling mounts but no spring lock washers for the horizontal storage area. Might be a problem later on. Another thing – don’t connect the 8×4’ section prior to lifting into place – put together only the two 4×4’ sections. It is easier to raise and install this way. Way too difficult to raise a 8×4’ metal grid above your head to install. I installed by myself – it would be a lot better if you have a buddy to help too.
Overall, I am very pleased with my purchase.

This storage has been something we have needed for so long. Like most people we’ve been short on storage space, especially for items we rarely need access to, like holiday decorations, birthday supplies, etc. Our main concern has been hanging storage over our classic car which is valuable and the risk of the storage racks falling.

The Fleximounts 4 by 8 foot storage has had awesome reviews and unlike other overhead storage out there I am confident in hanging storage over our car with this unit. We installed ours in two sections and into wood joists, but concrete ceiling is an option as well. The pieces come well packaged and the box contains all necessary screws, bolts, nuts, and thorough directions. There Youtube video is very helpful as well. This company includes 6 posts to attach to the ceiling where as most others on the market provide 4 which could cause sagging when storing heavier items.

With the overhead storage I have gained over 100 cubic feet of storage that can hold over 600 pounds. The whole unit appears to be powder coated and the steel looks to be 3/8 gauge. The welded wire racks make the contents being put onto the shelves more secure and the hooks Fleximounts provides is great for bikes or other items which need to be hung. The M8 bolts are also a differentiation and one reason the storage unit can hold so much weight, as said earlier over 600 pounds.

My wife is so happy now that they garage mess is cleaned up and things are tidier and put away in the air and we can park in the garage again. Happy wife, happy life!

I was really satisfied with the product, packaging & instructions. The only difficulty I ran into during assembly had to do with screwing the panels together. The threaded bolt holes seemed a little rusty. A little WD-40 and screwing a bolt into each hole before assembly helped assembly go better.

As I loaded things on the rack, I noticed the ends of the wire grid tended to catch the nylon fabric cases of some of the heavier items. It would have been nice if these had been beveled or rounded off.

Another review complained about the tools included. Fortunately I have a great socket so I didn’t have to deal with their answer for that. If you want to make assembly go easier, get a 5mm Allen wrench bit and use it with a drill or impact driver.

The other tool I recommend is this stud sensor the ProSensor T13 Professional Stud Finder (

Most of my installation problems were due to complicated ceiling structure. Verify the direction your ceiling joists run. If they run parallel to the direction you want to run your rack, you’ll need to change plans or improvise.

It is not the easiest thing to install but it is pretty easy to follow the instructions.

This works great and looks great. We are very pleased with the end result.

This rack is easy to install and really cleans up the clutter in my garage!

Love these shelves – they open up the room for twice the storage. Highly recommend.

This is the 3rd adjustable base we have purchased from Ergo. They are amazing! Everyone in the office loves them. The construction is very sturdy and the raising and lowering transition is incredibly smooth! We hope to convert more stationary desks in our office to these adjustable height desks! The customer service we have received from the company is impeccable!

Great, ended up calling support before I bought to ask about the products and great service, also after installing and using something glitched on a control module, but was able to talk to support and they sent a new one out. They mentioned that it is pretty rare for that issue.

Works great. The have very prompt customer service. My stand came with a bad power supply. After taking a few pictures and filling out an online form I received a replacement part in just a few days from their support contact.

This was well worth the money to allow me to work at multiple levels. Feels sturdy and is a great addition to my home office.

This company deserves 5 + stars. I purchased one of their bases about 2 years ago. I did not use it as a desk, I made a 52″ x 72″ card/game table to be adjusted at 30″ high and a seperate table top only to be placed on the card table for a quilting table to be at 38″ high. My wife wanted a separate room built for her quilting so we moved the table base to the new room, that is where our troubles started. I could not get both legs to adjust to the same height .Even though it was well out of warranty I called customer service for help, one of their tecks spent a good half hour having me try different things, when none of them worked, they sent me a new leg, and spent another half hour plus working with me but it still did not work. They sent me an entire new base which assembled easily and worked great. I offered to at least pay for the shipping buy they would have nothing to do with it. I have never worked with a company with such great customer service. I wish more companies would follow their business plan.

Purchased last Dec- started working from home almost 1 yr ago. Had a desk top version (sit stand)but saw the price on this and liked that it could be made to straddle a treadmill- or(since I added the wheels- purchased thru the company) moved away….. or to another room- yes! In front of my beautiful Christmas tree last December. Then back into another room with lower ceiling and cooler in the summer. Now however I’m back in the great room because the natural lighting is better. I’ve recommended this to 3 colleagues today who all are complaining of knee/ back /shoulder pain as well as other health issues. This product is very reasonable and you can’t put a price on losing mobility. Thanks!

Very simple assembly and still enjoy using it. I’d recommend putting loc-tite on the set screw though.

Awesome way to turn a cube into a standing desk !

easy attachment of top

I was very impressed with how the item shipped – quality foam inserts kept all the parts from bumping into each other and getting scratched. I was skeptical about what the quality and assembly would be as I have had back experience with purchasing ‘assemble at home’ furniture in the past. I had this all put together and operational in about 10-15 minutes. All parts went together very easily, screw holes lined up, all the parts were there and the instructions were very clear and diagrams accurate and easy to read. My company recently purchased sit to stand desks and they were thousands of dollars, this product rivals the quality of those at less than 10% of the cost. Very happy with the product so far!

I mounted a 3′ x 6′ 2 inch thick butcher block piece of wood on top of this thing, stained the wood, and now I use it as my standing desk. Super high-quality heavy duty metal. Substantial. I love the automatic control to raise it up or down with 4 memory locations. I am using this with the TR 1200 DT3 walking treadmill, a 350 pound limit high-quality substantial super quiet treadmill. Combined with this and a very heavy substantial desktop, I have a super high-quality standing office which I use every day, yesterday I walked 13.5 miles in about nine hours of treadmill use and got 11 hours of work done that day. Productive. Highly recommended

Great Price for a nice desk . It was pretty easy to assemble and seems to be well made. Raises and lowers easily. I made a top for it out of 3/4″ Birch Plywood and the side skirting is made out of 3/4″ Poplar and 1/4 birch. The only negative to the desk is that it is wobbly when fully extended.

So worth every penny. Simple to put together, threw on my old desk top BAM, done in like 20 min.

Love the desk so far, great price and works great. I bought a 72″ x 30″ butcher block and screwed it in. Pushes the weight up no problem.

I don’t usually write reviews and definitely don’t write them right away, especially on products like this since they need to stand the test of time. I bought this on January 6, 2016 and now has been more than 1 year I’ve constantly used it since I work from home and several things are sitting on this, including a large 27″ display, 2 Yamaha NS10 monitors (speakers) and other things. The desk has been operating sturdily without any issues. It’s still very stable even when all raised and the electronics/motor still working as expected. If I really had to be picky I’d say the only annoying thing is that you really have to unplug it at night (or turn off the power strip where you have it plugged) because there see to be a very low humming noise coming from the motor or electronics. It’s so low that you can barely here it so nothing major, but still that means electricity is till flowing there even when you are not operating the up and down buttons.

This desk frame is SOLID construction. I was very impressed with the quality of the frame. Ergo Elements also gets 5 stars due to their highly responsive customer service. I had a problem with my controller for the desk and they responded very quickly to resolve the issue without making me jump through hoops like many companies do.

Best product on the market. Easy to assemble and install and great customer service. If you are looking for adjustable legs, these are the ones you want.

Very easy to set up. The base is sturdy and well made.

My wife loves her desk. We’ve been using it over a year now, no problems.

Very happy with desk. Support quickly address an issue with the top being damaged on delivery. I wish I would have purchased this sooner.

Save much more space than I thought, now I could do more craftsman work as called by myself. Feels sturdy.

Sturdy and reasonable cost, takes time and energy to install though.

Some money and soem decent time of installation, my garage looks good now, would recommend this.

Bit of challenging to install. Over all, it worths the money.

Good quality and serves its purpose. Worth shot.

it really worked out better than I expected. There were numerous size options to make sure everything fit perfect. Very sturdy!

Great product. Directions could have been better, but we figured it out. We were short 3 screws but found some to fit in the tool chest. We’ve got it loaded up and couldn’t be happier.
