4 Inch Nylon Wheel Swivel Top Plate Caster Set with 2 Brakes 2 Rigid SCC

Features

• 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.
• Bolt size: 5/16" (hardware not included)
