5 Inch Heavy Duty Top Plate V Groove Semi Steel Swivel Caster with Ball Bearing

Features

• Top plate measures at 4-1/2" x 6-1/4" with a bolt hole pattern of 2-7/16" x 4-15/16" to 3-3/8" x 5-1/4" 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)
