• All casters feature a 7/16” diameter by 1-3/8” long grip ring stem. Service Caster recommends using a drill or hardware gauge, a 7/16” wrench, or our paper wrap method to ensure the grip ring stem diameter needed is 7/16”. Paper Wrap Method: take a small strip of paper and wrap it around the stem. Mark the paper with a pen where it overlaps, keep the wrap tight. Measure the strip from the start of the wrap to the mark. The ruler should measure 1-3/8".
• 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.
