Compact Dual arm 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.
- Innovative light weight construction.
- 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 had 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.
