A similar caster/floor mount moves multi-ton tools into position in the real shop to be encased in epoxy after machine set-up. Each has an adjustable 'handle' design with a three-position selector switch. Smooth deployment of the casters.
Fit and finish is good. These perform beyond expectations!
Bought 4 of these for my very heavy and large table and chop saw bench. Adjustable pads on each feet that help both with locking my workbench in place but also help with make sure the bench is level. This is what i needed to move shelving.
The wheels turn so easily that the workbench will start rolling on its own on my relatively flat garage floor. The table rolls smoothly and the tires are big and soft. It weighs about 500 lbs and theses work great for moving it around.
Caster locks work perfectly, easy to engage and disengage with my foot. Wheels lock individually and i only need to lock 2 to stabilize the table. The one thing i will say is they lock easy but to unlock is harder.
Worked perfectly in my new welding table. The work bench is 4x8 with drawers, power tools, vise. Using on a wood shop cart with a planer on top.
I believe they would pretty quickly deteriorate.
