QWORK 3" Caster Wheels for Boltless Shelving – 500 lb Load Capacity, 4 Pack Storage Shelf Accessories for Garage, Storage, Workshop, 8-11/16" Total Height, 2-1/16" Side Length

Needed a way to move a shelving unit in order to access enclosed trailer that I bring into garage for winter. These installed easily and work great. I especially like the locking funciton as when engaged, it locks the wheel from rotating and also the position of the wheel. This allows the shelving unit to remain firmly in place. The wheels are also very sturdy and quite heavy-duty. Excellent item and worth every penny.

Heavy duty wheels for a heavy duty rack. These wheels made it easy to move the big rack in the corner of my garage that I previously could barely lift the end. Although there were no instructions included, it was easy enough to figure out how to attach the wheels to the rack. It's nice that you can lock the wheels to prevent the rack form being accidentally moved. If you have one of those heavy duty racks and want to be able to move it while fully loaded, these wheels are a great solution. Please unload the rack first so you don't have it tip and kill you. :) And the price was quite reasonable. Highly recommended!

This definitely beats removing everything off my shelves and dragging/scraping them across the floor. Works well the rivet style shelves, casters seem very nice and heavy duty. I mostly keep motorcycle parts on my shelves, some heavier than others, but probably not close to the "500 lb" limit. There are no instructions so here's a little advice. 1. Make sure all the shelf rivets are clicked down. The whole shelf seemed wobbly until I realized when I moved the shelf to put the casters that a few of the shelves were twisting the everything making it uneven. 2. Put the bottom shelf in before installing the caster hardware otherwise you can't get it in. 3. Might be unnecessary, but they only give you 1 washer for each bolt which. I added a washer on each side just to increase the surface area being held. Overall I'm very happy with these. Each wheel has a lock which seems to function just fine. Another added benefit is I originally had the bottom shelf 2 notches up just so it was off the floor, now so it did open a little more space on the shelves. Ordered 2 more sets for my other shelves.

Nice caster wheels. Mine didn’t come with the hardware that was supposed to be included. I wrote the seller and asked that they send the screws and nuts but instead they offered a small compensation so I could buy some on my own. That actually worked out well as I ended up buying bolt screws, nuts and fender washers for a solid fit. Probably much better than the hardware that would be included. The L-shaped brace was a perfect fit. My table that sits on these casters is all metal and heavy but I don’t see any stress on the wheels at all and it moves very easily. Overall I’m happy despite having to deal with messaging the seller, waiting for a response, going to the hardware store to pick out the right sizes… unnecessarily frustrating.

Here is the problem with these wheels. The two bottom holes are too big. DUH! Only the top little slit will work. You buy these to put wheels on the knock together (screwless, or boltless) racks you get from the big box stores. ( Those racks are a nightmare to get wheels on. They are also nightmares to put together. I will never buy them again) I am now trying to put everything in my shop on wheels. I am stuck with some of these knock-together racks. These wheels come with tiny little fender washers that go right through the big holes. I looked for bigger fender washers but they don't exist. After several hours work, I suddenly realized that only the top narrow little slit was effective in holding these against the leg of the rack. I have to undo all my work except for the two bolts in the top slit. I'm going to experiment with some 90 degree angle brackets with holes in them. If that does not work, these are going back to Amazon. There is a different design that has narrow slits all the way down, and those do work. The wheels, however, seemed small to me. Under a big load, they failed. That's why I bought these, for the bigger wheels, but they won't go on!

I added this wheel casters to my Members Mark shelf and is working perfectly fine for the last few months, I painted them to match my shelf and color is pretty much matching seems like it came with them from store. As you can see is holding up nicely with all the items in my shelf and makes my life easier when is time to clean all the dirt under. Installation is easy enough if you have the tools because in my case the shelf angle posts hide the hinges so had to drill the holes where I installed the casters but no big deal it easy fix, good value for the money paid and rolls very smooth fit perfectly for my application. Highly recommended for those with fixed shelves in the garage and cleaning projects will be easier after the install.

The large holes will need large washers, that are not included. Other than that, they work great.

These were a great fit for our shortage shelf. These are holding up well to a significant amount of weight and movement around the garage a lot. They were easy to install and have not given us any issues.

Very cool item to have, quality of this product is excellent

Used it for my glass kiln. Works great. Makes a huge difference.

Castor wheels himself seem fine, but the brackets bent and the wheels buckled. I will take the wheels off and make a heavier bracket to put underneath the unit out of angle iron

I ordered 2 packs - both are really dusty and scuffed up, clearly used before and returned. One of them had the nuts and bolts just loose in the box even though there was an empty undamaged ziplock baggie; and the other one was missing the washers.
