QNCZ 4" Caster Wheels, Outstanding Casters Set of 4 Heavy Duty, Silent Industrial Casters, Locking Casters Wheels for Furniture, Castor Wheels for Cart, Workbench.

These are GREAT wheels. I used these to build a VERY large wood shelving unit out of 2x4s and plywood. About 8ft long and 7ft high, to hold x5 27gal bins on each shelf. This large of a shelving unit combined with the added weight of bin storage (give or take between 800-1000 pounds of weight), these wheels have held up to the test and make rolling around the shelving unit EASY.

Sturdy, reliable, great wheels

Delivered on time, quality is excellent, they came with both screws and nuts and bolts as to your preference on how you want to mount them, came with wrench and screw driver( you will need your own screw driver as the one supplied is a #1 phillips screw driver , you will need at least a # 2, most common, but a # 3 is what it takes, a # 2 will work)Installed and the roll effortlessly!Price is great, I highly recommend!

I've used these on two projects. A workbench that's very heavy, and my table saw. The bench unloaded weighs close to 100 pounds. It rolls across my garage floor and driveway with ease now. The locks are solid too.

I bought these based on a YouTube channel that I follow and said what the heck I’ll give them a try. They even have nuts and bolts and screws for installation. The included Phillips screwdriver and wrench are a bonus. Now those two items aren’t SnapOn quality but they’ll get these installed and will be good to add on the workbench. Overall a good purchase and priced right.

Well made. Operates flawlessly

The wheels are sturdy and hold up to the weight limit, roll ability has been consistent so far as well as the locking mechanism. The orange color makes these look awesome!

I own a US General 4-drawer tech cart in orange. I am not a professional requiring or owning a high volume of tools, but like most homeowners and DIYers, I have acquired enough over time needing to be organized. And I have limited space so the smaller cart worked. If you are familiar with these carts you know they come with 2-fixed and 2-swivel casters in all black. The OEM casters themselves are decent, and I figured I'd try to live with the more limited maneuverability of having 2 fixed casters. A week was enough to realize I wanted four swivels, and Harbor Freight doesn't sell the all black casters separately. I saw these 5-inch casters on Amazon and was first drawn to the black and orange theme which matches my cart. Then I saw the weight capacity which well exceeds the OEM casters. Then I measured the openings on my cart and these were a match. I installed them today (using the cart hardware) and the cart can now rotate in place if I want it to - no more "parallel parking". They seem to roll smoothly and support the weight of the box just fine. And I got 4 for the price of what 2 non-matching and non-braking swivels would've cost at HF. Not knocking HF, just wish the cart came with 4 swivels out of the box. First impression - just what I needed and look good as a bonus. Will update if anything makes me change my opinion.
