I found these casters http://www.greatlakescaster.com/great_lakes_caster___swivel_caster___3_x_125_non_marking_wheel_precision_ball_bearing_swivel_caster_with_total_lock_brake__12_13_x_1_12_threaded_stem-12-0312-BPX-S-T28-T.php?cat=206 when looking for parts for my brew stand build, I had to rub my eyes because I didnt think I was seeing the price correctly because a caster of this quality cost three times as much. The lock not only stops the wheel it also locks the swivel and are rated at 250 lbs, also ther are made in Brazil not China. I suggest lubing the swivel roller bearings for smooth rotation under weight when moving.
