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.
Wheel = wheel diameter · capacity is per caster.









Unlike a grip ring stem, a grip neck stem has a groove near its top. It snaps into a socket that is first tapped into a drilled hole in the wood leg. The socket's teeth hold it in the wood, and the stem can still be pulled out to change the caster [S1].

Other stems: 7/16 grip ring stem casters.
