Compact mainsheet jammer.
Allen have spent many hours of research and development with various boat builders to perfect the angle and height of the cleat to optimise mainsheet jamming.
- Fitted with aluminium ball bearing cleat AL-0076
- Innovative light weight construction
- Aluminium arm
- Dual ball race for maximum efficiency
- Optional click stops limit swivel rotation
- Line snags virtually eliminated
- Standard and high cleating angles to suit all
- c/w stand up spring, spring guard & low profile shackle
A groove has been created in the arm for the location of the ball bearings;
this design prevents the lateral movement of the arm, significantly improving
the play and friction associated with traditional jammers of this format.
