4 Piece Solid Polyurethane Caster Set with Ball Bearing Swivel Lock Brake

Features

• Top plate measures at 4" x 4-1/2" with a bolt hole pattern of 2-5/8" x 3-5/8" to 3" x 3" and can either be bolted or welded on.
• Brake options include a top lock brake (TLB) and a total lock brake (TTL). The top lock brake places a positive locking force against the wheel tread locking the wheel only. The total lock brake also places a positive locking force against the wheel tread, but the total lock brake simultaneously locks the wheel and the swivel for a complete stationary position.
