Capacity/Caster, and 8": 1250 lbs Capacity/Caster • Top plate measures at 4" x 4-1/2" with a bolt hole pattern of 2-5/8" x 3-5/8" to 3" x 3" and can either be bolted or welded on. • 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.
