This company's new Sidewinder machine for spiral ductwork forms material outside the head, which reduces scrap and makes head changes easy and fast. It requires little lubrication, so there is no mess and the finished ductwork is virtually dry, which means it can be painted or shipped sooner. It handles 3- to 50-inch diameter duct in 18- to 26-gauge galvanized metal. An optional second uncoiler is available (see photo). For a free informational video, call (800) 665-8089.
