This is the best castor for your workbench. I bought a set of double lock reels from the store and they were very good. These Steelex rollers are excellent. They roll very easily and the double locking feature works great. Weighing 150 pounds each, they easily hold my bench, miter saw, bench drill, portable table saw, miter saw, and disc sander. These casters make it easy to wheel the bench out of the garage and then back into place. The double locking feature keeps the bench from moving when I'm using it. With no dual brakes, you always get the easy movement of the caster wheels. I used four caster wheels to get the bench into hard to reach places so double locking was required.
