Feeder fasteners are made of stainless steel AISI 304 (V 2A). The color is black.
Inserts are made of fiberglass. Their strength does not allow the feeder to be deformed when the clamp is tightened. Inserts have protection against ultraviolet (sun) rays.
Thanks to the self-locking technology, tightening the clamp does not require an additional lock nut.
The screw is separated from the inserts by a metal plate, which prevents accidental piercing of the inserts and damage to the cable.
