4pc - Storage Rack Caster Wheels (Adapts to Boltless Self Locking Shelving Racks) (3" (1500 lb. Max Total Capacity))

Seems like a straightforward add on. Need to be able to move the shelves with a load however. Not clear what a “heavy” load is per the instructions (may be just a legal precaution) but will update once everything is assembled.Update: The whole point of casters on a rack is to be able to move the unit with a load. Not completely stacked with car batteries, but I’m happy to report it will handle 3 battery backups and a few computers. I had to drill some holes but I have them on a Sam’s snap together Member's Mark 5-Shelf Storage rack and they work great. A lightweight and well designed rack, these casters are a perfect match (with a little tweaking on the rack) Very smooth movement, even over a somewhat bump concrete basement floor. Very happy, worth the price for sure for the bracket-caster design.

I am really pleased with how well the casters work. They were easy to install, and they roll really smoothly. They are heavy, sturdy, and of good quality. The brakes are easy to use. Ordering a second set my other shelf.

A bit pricey but worth it. Very impressed with the quality and design. Fits the shelving units I purchased at Home Depot. Installation tip: make sure the wooden shelf is in place before you bolt on the wheels.

The media could not be loaded. I needed casters for my garage shelves before having the bare garage floor epoxy coated. I was looking for casters to make a base and attach to my shelves. I did not know these “ready made” casters existed until I saw them on Amazon.Here is my (mostly good) experience with the casters...*** PERFECT FIT – I have standard 78 inch high shelves purchased from the orange box store. No problem with the fit. See photos 2, 4 and 6.*** ADDED SHELF HEIGHT - The casters will add five inches to the shelf height. I had about one inch to spare when rolling the shelves out of my roll-up garage door. See photo 1.*** EASY TO INSTALL – The only tool you will need is a one half inch wrench. With each caster there are two carriage bolts with lock nuts and washers. See photos 2, 4 and 5.*** INSTALL TIP – If your bottom shelf will be below the caster bolts put the shelf (wire or wood portion) in place before attaching the bolts. If not you may not have enough room to tilt the shelf when putting it back on. See photo 4.*** LOCKING LEVERS – As other reviewers have noted the levers are plastic and can break. I used caution when locking the casters, but they would not stay locked. See attached video. Resolution is below...*** CONTACTING TOOL GUY REPULIC – I sent TGR a message thru Amazon and TGRs website. They responded the next working day. TGR offered to send replacement casters with a prepaid return shipping label. Great support. See more below,,,*** LOCKING LEVER PRESSURE – After taking a close look at the casters I decided to put more pressure on the levers when locking. I had to get to the point where the plastic lever started to flex. This worked. I declined the replacements from TGR.I'm rating four stars and dinging one star because of the locking levers. At $83.00 per set as of the date of this review the levers could be better. Overall the casters are sturdy with enough steel thickness to support the rated shelf weight. After discovering the TGR casters I could not find a similar product so I would buy again if I add another garage shelf.######## UPDATE 8/25/2022 ########I received a reply from TGR regarding the plastic locking levers. See below:"Thank you for letting us know. We really appreciate your feedback.We are already working with the factory to improve these for the next generation of the product. They will most likely include metal locking levers as you suggested."#################################

One of mankind’s greatest invention installed onto muscle and husky racks. Recently got floors resurfaced, and knew there has to be a better way when moving the racks outside for the resurfacing. Thanks to TGR for recognizing and fabricating this product to solve a common challenge! Doubt I’ll move the racks often but aside from mobility, the lowest rack is now 5-6” above floor. Makes life a bit easier when cleaning floors or getting stuff from the lowest rack. INSTALL TIP: 1) loosely install the bolt, washer n nut on ground; 2) tighten the nuts with this unit “resting” ON TOP of the rack leg. This method ensures the leg will “sit”, “rest” at the lowest point on this unit when nuts r being tightened. 3) if using a socket, position the bolts and nuts away from the other so that u can rotate the socket to tighten.

Love the product. It is well engineered, extremely sturdy, and high quality. Even the bolts are cut to exactly the right length and the nuts are locking nuts. The price seems high to me so I’m not sure it’s an excellent value, but there’s nothing else like it on the market and it is very well built and does the job very well.

I didn't like the price, but bought anyways. I needed something to fit my Muscle Rack shelves and something that could handle a heavy load. I actually installed on existing shelves without turning it over like instructions stated.... I took everything off the shelves but I didn't want to go through the pain of taking off all the shelves and supports so I just lifted each end up enough to get wheels under. It wasn't ideal, it made it harder to install, but it still worked. When I first rolled my heavy, full shelf around I was VERY surprised as to how easy it was to roll... in any direction.... I was so happy I wanted to do a little dance with my shelf (it was a long day, and getting wheels to make this shelf mobile was a BIG win for me!). In the back of my mind I kind of wanted them to suck cause I didn't like the idea of spending that much money on wheels. But now that I have them, I am IN LOVE and will definitely buy again when more are needed.

i have a bunch of those "boltless" shelving systems, and got the idea of rolling them around to make storage more efficient. there's not many casters out there designed to fit the rails on these things. i think i found 2. i went with these because they looked more sturdy than the others, and boy are they. these things are HEAVY. each caster probably weighs about 3-4 pounds. they bolt in through the top hole, and they have a little lip on the bottom inner edge to lock them into place underneath. the caster wheels are large and roll very smoothly. they're pricy, but i would definitely put them under "you get what you pay for"
