Allen Keyball Trapeze System
For many years the development team at Allen were keen to design a trapeze system that improves the safety of the sport and reduces the risk of entrapment by the traditional hook-on trapeze harness.

Designer Julian Bethwaite had also been thinking along the same lines and had produced a prototype of the keyball trapeze system. In conjunction with Bethwaite Design, Allen have developed the concept into a sleek and innovative design, eliminating the hook altogether and creating a safe intuitive solution that really works.

The ball and guide is manufactured from solid aluminium in three parts:-

· A solid aluminium guide with an integral rope-friendly thimble for attachment to the wire via a height adjustable rope.

· A flexible section joining the ball to the guide enabling articulation

· A solid aluminium ball for smooth and secure location

The buckle is manufactured from two parts and bolted securely together:-

· A 3D moulded keyhole with a wide opening guides the ball securely into place when trapezing whilst easily releasing when required.

· A stainless steel back-plate in either narrow or spreader format allow for easy changing to suit different designs of harness.
