Dual Arm Mainsheet Jammer

Allen Dual Arm Mainsheet Jammer

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.

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.

See diagram.

For use on:-

Etchells, Fireballs, sportsboats, SB3, Finn
