Insulation Fasteners
Gripnail Corporation is an employee owned company that manufactures mechanical insulation fasteners and welded insulation fasteners. Both systems fasten fiberglass insulation or foam insulation to metal. These systems are primarily used to fasten duct liner to sheet metal air ducts.
Gripnail mechanical insulation fasteners securely attach to supported sheet metal with impact. Gripnails may be applied with insulation fastening equipment ranging from a magnetic hand hammer to a high speed, hopper-fed, multi-head Pinner capable of applying 300 fasteners per minute. Single head, dual head and gliding head application equipment is also available.
Gripnail's PowerPoints are resistance weld pins which fuse to sheet metal during application. PowerPoint Weld pins may be applied with a hand held welder, a hopper fed welder, a gliding head welder or a high speed multi-head welder. Each weld pin is formed with a diamond shaped point for fast, secure welds. Gripnail's Power Pinner welding equipment has been specifically designed for fastening 2 inch duct liner.
All fasteners and application equipment are manufactured in East Providence, Rhode Island and sold around the world by leading distributors of heating, ventilating, and air conditioning supplies. Call or e-mail to find out more about our products or to locate your nearest distributor.
