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 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.
