The Preformed Armor-Grip Support is intended for use on Aluminium based conductors, and is designed to be used with clamp top horizontal and vertical line post insulators.

The Preformed Armor-Grip Support is designed to reduce static and dynamic stress at the support point, so that the conductor is better able to withstand the effect of vibration than with Armour Clamp attachments. Preformed Armor-Grip Support protect against clamping fatigue through bending and compression stress and against flash over arcing.
