Product description

Impact Driven Duct Lining Fastener

Gripnail is a proven mechanical fastener used to attach insulation to the inside of sheet metal duct work. The hardened tapered teeth pierce the duct liner and form a positive attachment to the sheet metal. Each fastener is precisely formed to exacting quality control standards and they may be applied with a variety of tools or equipment. Gripnails only work when the sheet metal is supported by a hardened base plate or the anvil of a Gripnailer^®

Product Features

Impact Fasteners

Bites into, but does not puncture sheet metal.

Cycle Time

Gripnail and sheet metal bonding is instantaneous.

Hardness

Point, shank and head are heat treated in a controlled atmosphere to hardness of Rockwell C-50.

Corrosion Resistance

Gripnails are plated with zinc and receive a final chromate dip.

Technical Data

Retaining Cap

The beveled edge retaining cap is designed to depress the surface of the insulation without tearing or cutting into it. The nail does not protrude from the cap, eliminating air stream noise or interfering with air displacement in the duct.

Temperature Range

Gripnails function properly over normally accepted operating range of temperatures of 32 ^oF to 250 ^oF and are not adversely affected at temperatures of 0 ^oF to 550 ^oF.

Vibrations

Gripnails will not fatigue or be physically affected by vibrations normally found in high velocity air handling systems.

Environmentally Safe

When used as intended, Gripnails are non-toxic and safe as defined by current Federal Standards.
Use standard personal protective equipment when applying fasteners at all times.
