4 Piece Heavy Duty Phenolic Caster Set

Features

• Top plate measures at 5-1/4" x 7-1/4" with a bolt hole pattern of 3-3/8" x 5-1/4" to 4-1/8" x 6-1/8" 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.
• Bolt Size: 1/2" (hardware not included)
