Description
Standard 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,
- 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
- Angle of rotations – 180, 220, 360
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. See diagram.
For use on:-
Sports boat, Keelboat, Etchell, SB3, Finn and many others
