These were exactly what I needed to keep my huge and heavy sand blast cabinet mobile so I can move around my garage to clean every now and then. My only issue is the moment I put these on one of the legs the bolts welded to the base for the 3 wheels sheered off. The tack welds had absolutely zero penetration into the base plate. The welds looked more like glue spots. I had to wire wheel the paint away and reweld them back on. None of the other leg casters had this issue and I’ve moved this blast cabinet around a lot. Aside from that one issue these are sturdy and makes moving around heavy objects very easy. I would buy again. Btw I did drill a hole and bolt these to the legs of the cabinet to prevent them from sliding around when mobile.
