Duro Dyne 26229 Ctc Sloped Washer Weld Pin Insulation Fastener

Product Description

The DURO DYNE 26229 is a CTC-series sloped washer weld pin designed to secure duct liner to sheet metal ductwork during HVAC fabrication and installation. The pin features a precision-formed point that consistently penetrates duct liner material, making firm electrical contact with the duct surface. Once placed, a compatible pinspotter welds the fastener in position. The 26229 measures 0.13 inches in diameter with a washer thickness of 0.015 to 0.017 inches. HVAC sheet metal workers and duct fabricators install these fasteners as part of standard duct liner attachment procedures in both new construction and retrofit applications.

This weld pin is used in commercial and residential HVAC ductwork applications where insulation liner must be mechanically fastened to the interior duct surface. The sloped washer design distributes holding force across the liner face to reduce pull-through. Compatible pinspotter models include the MF, PBF, FG, RH, FGMH, and HSMH units from DURO DYNE, making the 26229 a standard consumable for shops already running this equipment.

Key Features

• Sloped washer design distributes clamping force across duct liner surface to reduce pull-through
• Precision-formed point ensures consistent penetration depth through liner material
• Electrical contact weld process locks the pin to duct sheet metal without adhesives or mechanical fasteners
• CTC series designation confirms compatibility with select DURO DYNE pinspotter models
• 0.13-inch pin diameter suits standard duct liner attachment applications

Compatibility

Designed for use with DURO DYNE MF, PBF, FG, RH, FGMH, and HSMH pinspotters. Intended for securing duct liner to sheet metal ductwork in standard HVAC fabrication applications.

Installation Notes

Installation is performed by licensed sheet metal workers or HVAC technicians using a compatible DURO DYNE pinspotter. De-energize and lock out the pinspotter per manufacturer procedure before loading or clearing pins. Position the liner against the duct surface before firing to ensure proper weld contact. Follow applicable SMACNA guidelines and local mechanical codes for duct liner fastener spacing requirements.
