Doughty Clamp - Half Coupler 50mm

The Doughty Half Coupler 50mm is the Basis of the range of Doughty Clamps. This robust Doughty Clamp has a slotted base to captivate an M12 Nut or Bolt, enabling users to create fixings suited to their own individual requirements.


Doughty T57000 / T57010 combines strength and durability with a high degree of safety. They are designed to attach to round tubes or truss chords and suspend equipment and luminaries in the entertainment industries, e.g. film/TV, theatre and concert halls. These sturdy stage lighting clamps provide a better grip to the tube by wrapping it around, so they are also called ''Wrap-Around Clamps''.
