Review on Ultimate Swivel Locking Polyurethane Screwdriver: Unmatched Protection for Precision Tasks by David Romo

I plan to use these casters on my workbench in the garage. They were easy to install with just 4 screws and a washer. It came with screws and a washer which is good and a screwdriver. I had 2 extra screws. They are said to be able to carry up to 600 pounds. I tried attaching mine to the bench I had but had trouble because the bench legs are 4x4 and the casters are small, 2 3/4" x 2". I had to add casters to the edge of my 4x4 leg and didn't like that the back 2 inches had no support. But they held up my bench. I haven't tried rolling yet. I'll try this on the smaller bench I have.
