4 Inch Semi Steel Swivel Top Plate Caster Set with Total Lock Brake SCC

These Service Caster Series #20 Semi Steel Cast Iron casters offer various wheel sizes and mounting heights: 3” Wheel: 4-1/8” mounting height; 4” Wheel: 5-1/8” mounting height; 5” Wheel: 6-1/8” mounting height. Weight Capacity: 3", 4", and 5": 300 lbs Capacity/Caster Top plate measures at 2-1/2" x 3-5/8" with a bolt hole pattern of 1-3/4" x 2-7/8" to 3" and can either be bolted or welded on.

Brake options include a top lock brake, a total lock brake, or a posi lock brake. The top lock brake places a positive locking force against the wheel tread locking the wheel only. The total lock brake simultaneously locks the wheel and the swivel for a complete stationary position.

The posi lock brake places a positive locking force against the wheel tread similar to the top lock brake, but the pedal is located above the wheel tread rather than on the side of the wheel.
