Festool 500312 CT Wings Extra Hand utilizes suction from a CT Dust Extractor to provide additional support for mounting long items to a wall, such as molding, or for holding a straight-edge or level in place during layout marking. Featuring 16 adjustable "wings," the CT Wings quickly adapt and conform to molding and other stock while ing a tacky grip surface that minimizes movement. A bypass valve allows for quick and easy release and reset without needing to return to the extractor. This handy tool acts as an extra hand to hold materials, levels, or straight edges securely, accommodating various thicknesses up to two inches. It attaches easily to standard dust extractor hoses and supports weights up to 6.6 pounds, making it an essential accessory for precise and efficient work. Model Number: 500312
