Insulation dome caps and washers are made of stainless steel dome shells with self-locking washers. It is typically used to cover the tie of lacing anchor pins, quilting pins, self-adhesive-stick insulation pins, and perforated insulation hangers when installing insulation mats or jackets.

The dome cap can be made of stainless steel, galvanized steel, aluminum alloy, or plastic. It can undergo surface treatments such as polishing, zinc plating, and white or black spraying. Caps are available in different diameters and can be customized with cut holes for various insulation pin applications.

Domed caps with self-locking washers are designed to secure insulation pins and cover the sharp ends for safety purposes. When using heavy insulation, it's important to use a self-locking washer to secure the insulation and then install the dome cap to cover the pin end.

It is crucial to measure the pin length before installing the dome cap. For the best results, the pin length should be 1/4” longer than the insulation thickness.
