TRIMFAST® SYSTEM FOR FIBER CEMENT AND WOOD MOLDING. The Model 110A tool drives AST-075 finish pins to attach popular trim materials to steel 68mil (14ga) and lighter. The tool features an easy-load magazine, compact design and lightweight. This new and improved model had adjustable overdrive control, directional exhaust port, and last nail lockout to prevent blank firing. At 100psi maximum air pressure, the tool consistently countersinks the fasteners even when used with hardwood moldings. The tool comes standard with a durable plastic carrying case. For heavy duty applications like fastening to masonry or those that require fasteners longer than 2"", see our Model 210.
