Clamping
Helical Clamp
2006 – C3
Snapshot
Self locking helical connector which defines a reliable interference fit. The weakness conferred by the slot is helical and therefore consistent under variable load conditions.
Applications
Construction, pipes, furniture, & general assemblies.

Twin Helix Clamp
2009 – C4
Snapshot
Self locking twin helix which defines a reliable interference fit using the principle of a
Chinese finger trap. Shorten to insert the pipe parts, and spring form then self locks.
Applications
Plumbing, gas pipelines, construction & general assemblies. Very resistant to shock, flexure, and thermal variation.

Helical Wire Strainer
Snapshot
Self locking helical connector and tensioner for conventional fencing wire, which defines a reliable interference fit. The locking element is self locking and helical and therefore increases under higher load conditions. Variations can be single ended (as shown), double ended, or attached to other termination details. The device can be designed to be (1) pre-stretched prior to wire/cable insertion and then (2) subsequently released to add extra tension to the wire/cable.
Applications
Connection and tension of wires, cables, and stays for agricultureal marine and general application
