Polyurethane on Cast Iron Swivel Top Plate Casters Set of 4 Heavy Duty with 4 Inch Red Wheels - Includes 2 Swivel and 2 Rigid – 2,800 lbs. Total Capacity - Service Caster Brand
All wheel sizes have a 3/4" axle bore and a 3-1/2" hub length. When the spanner bushing is removed, all wheel sizes can be used on a 1" axle. Please keep in mind, the hub length is the widest point of the wheel, so it is important to ensure you can accommodate this width before purchasing.
Brake options include a top lock brake (TLB), a total lock brake (TTL), or a side lock brake (SLB). The TLB places a positive locking force against the wheel tread, locking the wheel only. The SLB places a positive locking force against the wheel hub, locking the wheel only. The TTL also places a positive locking force against the wheel tread, but the TTL simultaneously locks the wheel and the swivel for a complete stationary position.
