Beveled edge cap

Prevents tearing of duct liner

Faster welds

Forged diamond point design creates more electrical resistance for faster welds.

Better plating

Zinc and copper plating exceeds SMACNA standards and gives a more professional appearance.

Reduced down time

Consistent point quality reduces frequency of machine adjustments.

Stronger welds

Hardened steel point assures positive electrical contact for complete sheet to pin fusion.

Applied with standard equipment

Easily applied with automatic pin welder or most standard hand held or hopper fed resistance welders.

Item: Cup Head Insulation Pins

1. This product is usually applied with a capacitor discharge stud welder.

2. The method of application is to place the insulation onto a metal surface, push the cup head insulation pins through the insulation, and weld affix (mount) the entire fabrication in one step.

5. Cup head insulation pins are widely accepted as labor saving fasteners in the thermal and acoustical insulation markets primarily for commercial type insulation applications.
