Allen 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 optimize 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 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.
