Threaded Stem Caster w/Roller Bearing - 4" Wheel & 12MM Stem

Features

• These Service Caster Series #20 Semi Steel Cast Iron casters offer various wheel sizes and mounting heights: 3” Wheel: 4-1/8” mounting height; 4” Wheel: 5-1/8” mounting height; 5” Wheel: 6-1/8” mounting height.
• Weight Capacity: 3", 4", and 5": 300 lbs Capacity/Caster
• All casters feature a 12mm diameter (1.75 TPI x 2-1/2”) threaded stem. Threaded stems can be difficult to measure. Service Caster recommends having existing threads checked on a thread gauge to determine correct thread size before ordering.
• 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.
