The Makita 1-3/4" Roofing Coil Nailer (model AN454) combines rugged construction and robust performance with less weight (only 5.2 lbs.). The AN454 accepts standard .120 shank diameter coil roofing nails from 3/4” to 1-3/4” nails in length. The AN454 is engineered for longer tool life with durable and lightweight aluminum housing and an easy-loading adjustable canister. Ease-of-use features include a "tool-less" depth adjustment engineered for more precise control and flush nailing. Additional features include large carbide inserts on the nosepiece for long lasting performance. Oversized steel wear plates are engineered to reduce abrasion on the tool.
