The Doughty Half Coupler is the basis of the range of Doughty Clamps

This robust Half Coupler has a slotted base to fit an M12 Nut or Bolt, enabling users to create fixings suited to their own individual requirements.

The Doughty Half Coupler combines strength and durability with a high degree of safety. 
It is designed to attach to 2'' diameter round tubes or truss chords and suspend equipment and luminaries in the entertainment industries, e.g. film/TV, theatre and concert halls.

Due to the increasing number of outdoor events using truss roof systems etc, we supply the Half Coupler with stainless steel fasteners. This truss clamp is ideally used outdoors for prolonged periods while minimizing any galvanic corrosion.
