The Twenty Clamp is a aluminium pressure die cast clamp designed to suspend luminaires up to 20 Kg.

This Clamp can be secured to tubes with a diameter of 48 - 51mm with just two turns of the Doughty Knob. Luminaires are secured via a captive M10 or M12 Bolt (M10 supplied).

Damage to tubes and trussed is eliminated by using an extruded trigger.
