4 Pieces Polyurethane Wheel Swivel Expanding Stem Caster Set (Set of 4)

Features

• All casters feature an expanding stem that is 2-11/16” in length. The expanding stem comes in 10 different diameters: (3/4”, 7/8”, 1”, 1-1/8”, 1-1/4”, 1-3/8”, 1-1/2”, 1-5/8”, 1-3/4”, and 1-7/8”). Before ordering, Service Caster recommends measuring the inside diameter of your tubing, this measurement will determine the corresponding expanding stem diameter needed.
• Brake options include a top lock brake or a total lock brake. The top lock brake places a positive locking force against the wheel tread locking the wheel only. The total lock brake, which is featured on all wheel sizes, also places a positive locking force against the wheel tread, but the total lock brake simultaneously locks the wheel and the swivel for a completely stationary position.
• Wheel hardness: 60 Shore durometer
