All measurements indicate the wheel diameter by the tread width.

The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.

W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.

Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.

Frequently Asked Questions

What is a grip ring stem caster? ›
A grip ring stem caster uses a push-in friction-fit stem with a metal ring that grips the inside of a socket. Push the stem into a round hole on your equipment leg and the grip ring holds it in place. No tools required.
What socket size do grip ring casters fit? ›
Standard grip ring stems fit 7/16″ inside diameter sockets, the most common furniture and equipment socket size in North America. Always measure your socket opening before ordering.
Are grip ring casters good for office chairs? ›
Yes. Grip ring TPR casters are the standard replacement for office chair casters. Non-marking gray TPR wheels protect hardwood and carpet without scuff marks.
