AUEAR, 4 Pack 1.5 Inch Rubber Caster Wheels Heavy Duty Fixed Black Casters with Rigid Non-Swivel Top Plate for Furniture...

The mounting flange on this caster is way too small. The mounting holes are directly over the wheels and there's way too little room to install a proper size bolt. If they had lengthened the flange by just 1 inch, that would have allowed me to install properly sized bolts. As it is, I had to use 5/16 x 1" lag bolts, and they would just barely fit into their holes because of wheel interference. So, I had to drill the mounting holes first, force the bolts into their holes, and while holding the caster up in the air above the holes, I had to start each of the bolts in by 2 or 3 turns. Additionally, because of the flange size, the bolt heads were almost touching the mounting flange so that there's not enough room for a box wrench. You have to use an open end wrench, and screw each bolt in one flat ar a time. It's an enormous PITA. With all of that said, I gave these 3 stars because in every other way they seem sturdy enough. BTW, because of the space issue that I mentioned, you CANNOT use a screw driver to mount these or a ratchet. It MUST BE an open end wrench. Not a very friendly or well-thought-out design. :-(

I'm not using them for a cabinet to roll around. I installed one of them on the upper top corner of the door on my trailer. When I use a tarp for an awning, the wheel prevents the sharp corner of the door from cutting the tarp as the door opens. The tarp rides on the wheel instead.

Well-built, works perfectly for what I need them for. I have some old steel cabinet drawers that I use for storage under my shop bench. These castors work great for rolling straight out and back in.

Worked perfect to replace the caster from a sleeper Sofa. No Hardware store I went to had the perfect size.

The casters work very well, plenty strong enough. I took a star off because the holes are a smidge too close to the wheels; had to put some of the screws at a slight angle. It worked, but could have been easier if they were spaced out another 1/8 inch.
