SPACECARE Workbench Casters, Heavy Duty Retractable, 800Lbs Capacity, Set of 4, Steel & Urethane, Swivel, Retractable Height Adjustment, 360-Degree Swivel

These casters work as expected. I purchased them with the mounting plates from Powertec. I can’t comment on whether this combo can hold 800 lbs, my bench does not weight that much. I don’t know what it weighs but it is perhaps 350 lbs. The casters and the mounting plates are very convenient as a package. A word of warning, any casters like this will twist your bench as only one leg can be lifted at a time. That said, some people have attached a bar between 2 casters so both can be raised or lowered together. I have not done that but like the idea.

Super 👍

It’s excellent

Very impressed with this product, just what i needed.

The SPACECARE Retractable Workbench Casters Kit is like giving your workbench a set of monster truck wheels—suddenly that 600 lb beast glides around the shop like it’s on roller skates. The heavy-duty design feels rock solid, and the retractable feature means you can roll your bench into place, then lock it down so it won’t budge an inch. Installation is straightforward, and once mounted, they make moving bulky workbenches, tables, or cabinets almost effortless. If you’ve ever pulled a muscle trying to shove a heavy bench across the garage, these casters are the upgrade you didn’t know you desperately needed.
