• All casters feature a 12mm diameter (1.75 TPI x 1-1/2”) threaded stem. Threaded stems can be difficult to measure. Service Caster recommends having existing threads checked on a thread gauge to determine correct thread size before ordering.
• 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.
