HI-MOD Fail Safe Insulators utilise the same features that have made the Hi-Mod compression fittings so popular, this insulator has an internal ball-socket in the main body that threads onto the connecting stud.
The Nut is insulated from the stainless steel body by a Tufnol socket, preventing electrical transference to the insulator body or opposite terminal.
Should for an reason the Tufnol be compronised, the nut will bottom out against the stainless steel housing, while the back stay will loosen, the insulator will remain attached allowing the rig to be re-tensioned until a repair can be made.
