• Brake options include a top lock brake (tlb) or a total lock brake (ttl).

The total lock brake (ttl), which is featured on all wheel sizes, 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.
