Simply tighten the topmost knurled nut to compress the rubber for a snug fit. For added security, further compress the rubber with a wrench via the nut under the swivel raceway. Finely crafted with a bright zinc plated finish, heat-treated ball bearing raceway, and a gray polyurethane wheel, this versatile caster is ideal for work tables, shop projects, or any equipment with round or square tube legs. Service Caster is unsurpassed in quality, reliability, and excellent customer service. Count on us to move you forward.

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. Not sure how to measure or don't see the size you need? Call us or send us a message. • Brake options include a top lock brake (TLB), a total lock brake (TTL), or a posi lock brake (PLB). The top lock brake (TLB) and the posi lock brake (PLB) places a positive locking force against the wheel tread locking the wheel only. The total lock brake (TTL) also places a positive locking force against the wheel tread, but the total lock brake (TTL) simultaneously locks the wheel and the swivel for a complete stationary position.
