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.

Compression Brake Casters automatically lock the wheels as soon as weight is applied to the office chair. It only takes as little as 12-15 lbs of weight for the compression casters to lock. Self Braking Casters utilize a special friction brake that automatically engages and locks the wheel as soon as weight is applied to the chair. These types of chair casters are a requirement for safety standards within many industries including, retirement homes, nursing homes, hospitals, surgery centers, physical therapy centers, rehabilitation centers, and even corporate offices where the office chairs need to remain in one location when being utilized. When the person is not sitting on the chair, it is very easy for the chair to be maneuvered around. As soon as weight is applied, the chair will remain in its place.
