Allen Mainsheet Jammers


Allen Mainsheet Jammers

Allen Mainsheet Jammers have had many hours of research and development to give the best possible product. The range features our World leading cold forged bearing system which has a ball locating groove for smooth rotation whilst preventing the lateral movement of the arm. The angle and height of the cam cleat has been carefully designed to optimise mainsheet jamming and release when required. The angles of rotation can be set to 180, 220 or 360 degrees.

The A5266 range has the block mounted behind the swivel centre and angled towards the cleat. This creates a turning force on the block and jammer, meaning that the cleat will always be forced to point away from the boom and towards the helm ensuring the rope is to hand.
