The Failsafe Insulator, with features similar to the other Hi-Mod fittings, uses an internal ball socket in the main body which threads onto the connecting stud. The nut is insulated by a Tufnol socket, isolating the antenna from the opposite terminal. If the Tufnol insulator fails, the nut will bottom out against the stainless housing. While the backstay will loosen, the insulating studs will stay attached to the insulator body, allowing the rig to be re-tensioned until a repair can be made. Available by Special Order with toggle terminals, eye or fork ends to suit any application.
