If you've experienced your roller starting to slip off it's frame while you are painting and/or you've wrestled with getting it off the frame when your project is complete you will love the Shur-Line Easy Release frame. Simply slide any 9" roller cover over the frame， lock it in place， paint， and then unlock to release the cover with no mess. Simply click n' drop your paint filled roller cover into a bucket of water or can. A patent pending cage prevents roller slippage while painting and the ergonomic comfort grip 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.
