Insulation Dome Caps




Aluminum Insulation Dome Caps are both lock washers and protective caps that conceal the sharp end of a pin.  Dome caps can be used as a locking washer on both Perforated Base and Self-Stick Insulation Hanger Pins.  The aluminum dome cap contains a stainless steel lock washer on the inside and creates a safe and an attractive look if left exposed.  Dome caps can come in silver or painted black or white to match insulation facings or fabrics.
