BTM UniCroc Hand Held Clinching Unit

Pneumatically operated hand held clinching unit designed to join standing flanges.

UniClinch with Crocodile Action

The UniCroc uses a lever action mechanism to provide access to standing flanges by offsetting the clinch tooling away from the integrated air-hydraulic cylinder. This also provides a more ergonomically correct manual positioning of the tool to the joint location especially when suspended vertically above the part. This unit facilitates faster production through ease of positioning and better vision of the joint location.
