Usage Instructions
Dome caps are ideal for applications where appearance and safety are priorities. For optimal results:
Select pins that are 1/4 inch longer than the insulation thickness
Secure insulation with a self-locking washer first
Install the dome cap to cover the nail point
Silver dome caps are economical and can be painted to match any color
Black dome caps are preferred for black fiberglass acoustic board or black fabrics
White finish washers are used on ASJ faced material or white fabrics
