HF is a place that has real bargains in casters. I have many casters from there. I have never had a failure. Don't tell anyone but my old wood storage rack had over 1700 pounds of wood on it---supported by four 300 pound load HF casters---need I say more?
Well I guess I do. You may have seen pics including the two 7' tall 2' x 4' yellow cabinets I have. They have been on HF casters for something like 30 years. The drawers are full of pliers, screwdrivers, drills, saws, wrenches, files, knives, chisels, etc. The cupboards on top have 4 routers, steel centering sets, scrapers, portable vises, all kinds of unusual hardware for a woodshop---like circlips, e clips, etc. They are way overloaded. Once you overcome the initial inertia to get them moving you can move them across the shop with one hand. You get the idea, I am a HF caster fan.
Enjoy,
