Manufactured from pressure die cast aluminium the Twenty Clamp has been designed to eliminate truss damage usually associated with Steel Hook Clamps.
This neat and compact clamp has a SWL of 20 Kg and can be secured to tubes of 48 - 51mm diameter with just two turns of the Doughty knob. Luminaries are secured via a captive M10 or M12 bolt in the base of the clamp.
