Derwent Clamps® were recently added back into the Derwent range with a new state of the art robotics manufacturing facility being established in North East Victoria.

The Stainless Steel Clamps (Kawandah®TM - Cocky Clamp) were developed for the Australian and export markets  by the Evans Group of companies in 1981, in Wangaratta Victoria. The iconic logo of the cockatoo (Current trademark) is the logo we are still proud to use today to represent the range.

Derwent Industries manufacture and distribute under the Derwent brand the range of 316 Stainless Steel Clamps.
