Allen A4043N-1 Moulding with Square Backing Plate for Keyball Trapeze System.

Allen Keyball Trapeze System Backing Plate - Square

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, or cause damage to the hull of your boat

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.
