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? 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.
