This "stake lock" collar (no washer used) blocks rear resin entry and seperate the roller from the rear of the handle. Phillips screw seals threaded section and makes dis- assembly convenient. Counterbore size is minimized to reduce resin entry. Uses 1/4" (5/8" + diameter) and 3/16" (3/8" & 1/2" diameter) frame material sizes.
