Review on Seismic Audio CASTERS Locking Non Locking by Arturo Reyes

These casters are good, but you may find yourself doing better with others at a lower price. I have a woodworking shop where most of my equipment is mounted on carts or frames so I can move things around. As a result, I bought several sets of rollers. The height of the locking and non-locking elements is so different that the frame blocks the turning function. The locking tab is also harder to reach than most.
