Doughty T5812201 Clamp - Half Coupler (Super Lightweight)

The Doughty half coupler T58122 / T5812201 is an upgraded Super Lightweight Clamp with very positive feedback on the changes after listening to customers. It solves the old problem which the clamp knob fell to the ground when working at height.

It is an ultra-lightweight half coupler clamp with a weight of 0.18kg, only 29% of the standard one's. With a slotted base to captivate an M10 Nut or Bolt, it enables users to create fixings suited to their own individual requirements. 

Widely used in the theatre, film, TV and photographic industries to attach round tubes or truss chords and suspending luminaries.

"We listened to a lot of our customers who said that when working at height it is often frustrating when the knob of the clamp spins off and falls to the ground. We've made some changes to the eyebolt and made the knob captive so that it can no longer fall off. We have also increased the SWL to 100kg from 75kg which we hope will please everyone who is already a loyal user of the clamp." - Mark Chorley, Design Engineer at Doughty Engineering
