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.

Softer, higher-rebound polyurethane treads and geometry that lower start-up and roll force versus hard iron or phenolic on the same load. Hamilton brands those lines Ergo-Tech and Ergo-Glide.
Hamilton Pronto stocked models ship fast when on the shelf. Other Hamilton ergonomic builds can take longer. Read the listing lead note.
