If you've experienced your roller starting to slip off it's frame while you are painting or a sore arm after a short time rolling you will love the Shur-Line Premium Grip frame. Simply slide any 9" roller cover over the frame to lock it in place to get started. The patent pending Hold-Tite roller cage prevents roller walk-off while painting. Non-slip, cushioned handle design provides hours of use with less fatigue. The threaded end allows you to attach any standard extension pole so no project is out of reach.
