Easy to install, comes with instructions. Retrofit Humphrey's 8" casters with these brakes. Caster is not included. Packaged as a set of 2 brakes.
Please Note: In order to install these on existing 8" Humphrey's casters, the yolk (metal part) of the swivel caster must have the little metal nub on it where the brake hooks in.
These will only install on the swivel casters.
