Features:
· This fastener forms a permanent bond to the duct work by becoming part of it as in any weld. Two styles are currently in use. The first fastener is a mechanical fastener which is driven through the liner and welded to the duct work underneath. The second fastener is a pin which is welded to the duct work prior to the insulation. The liner is then impaled (much like the adhesive fastener) over the pin and secured by a washer.
· Designed to meet SMACNA HVAC Duct Construction Standard for Mechanical Fasteners.
· All steel used in Duro Dyne Insulation Fasteners meets ASTM-A591.
· All dimensions used in pin length are from bottom of head or base of fastener.
