Bolt hole casters have a hole in the rivet which can accept a bolt or a customized stem for any type of mounting requirement. Brake options include a top lock brake, a total lock brake, or a posi lock brake. The top lock brake places a positive locking force against the wheel tread locking the wheel only. The total lock brake simultaneously locks the wheel and the swivel for a complete stationary position. The posi lock brake places a positive locking force against the wheel tread similar to the top lock brake, but the pedal is located above the wheel tread rather than on the side of the wheel.
