Compact 4-inch Roller Frame

The Wooster R017-4 is a mini paint roller frame designed for small-area coating tasks. Its cage-style construction accepts 4-inch roller covers for detail work on trim, cabinets, or touch-ups. The 15-inch overall length provides extended reach without a separate pole. This tool suits painters and DIY users who need manoeuvrability in confined spaces.

Cage Frame and Threaded Handle Limits

The cage-style end cap holds the roller cover securely but requires the cover to match the 4-inch length exactly. The threaded plastic handle accepts standard extension poles, yet the 5/16-inch shank wire diameter limits the frame to lightweight roller covers only. Heavier nap covers may bend the shank under pressure. The frame is rated for all paint types but not for industrial textures.

Simple Assembly with Alignment Care

Installation consists of sliding the roller cover onto the cage and screwing the handle into the reinforced threads. The green polypropylene grip resists slipping during use. The most common issue is cross-threading the handle if started at an angle; starting the threads by hand prevents this. Chrome plating on the shank resists corrosion but can chip if dropped on concrete.
