Brake options include a side lock brake (SLB) which applies a positive locking force against the wheel hub which prevents the wheel from moving freely, or a bolt-on swivel lock (BSL) that when inserted into one of 4 notches found on the swivel raceway converts a swivel caster to rigid for straight-line tracking at any 90 degree angle.

Combining both brake types ensures complete immobility over both swivel and wheel on the caster.
