Type CFA insulating covers are made of high impact, high density polyethylene to insulate H-tap CRIMPIT™ compression connectors. Overlapping flash barriers protect both seams against possible electrical flashover. End fingers remain closed or wrap closely around conductors. Multiple latches lock cover closed securely. Type CFA-FR flame retardant insulating covers are made of high impact, high density polypropylene with a minimum 28 oxygen index. This cover incorporates all the features of the CF design plus the benefit of self-extinguishing flame retardant properties. Material is UL 94V-O rated.
