Reversible Armour Clamp (RAC)

Reversible Armour Clamp

The original RAC clamping system was invented by Hawke and is a well established proven performer in all conditions. Simply by reversing the clamping ring, the cable gland can adjust to accommodate all types of cable armour or braid. Unlike many of our competitors, the correct stamping orientation is marked clearly with the armour size and backed up by the presence of a groove in the component. Our RAC clamping system is also fully inspectable when positioned on the cable.
