The new HEADLOCK Paint Roller Frame locks paint roller covers onto the frame for faster and easier painting with less mess. Since their invention in the 1940s, paint rollers have become one of the most widely used paint application tools around the world. Despite their popularity, paint roller covers tend to slide and move on the frame resulting in loss of productivity and messy correction efforts. Patented HEADLOCK technology solves this problem with a retaining cartridge featuring a positive locking and release mechanism. The practical use benefits enhance the sporty appearance and ergonomic handle for a leading total use experience.
