Mainsheet Jammers

Allen Mainsheet Jammers have had many hours of research and development togive the best possible product.  Our mainsheet jammer range uses our World leading cold forged bearing system which has a ball locating groove forsmooth rotation whilst preventing the lateral movement of the arm.  Theangle and height of the cam cleat has been carefully designed to optimisemainsheet jamming and release when required.  The angles of rotation canbe set to 180, 220 or 360 degrees. The A5266 range has the block mounted behind the swivelcentre and angled towards the cleat. This creates a turning force on the blockand jammer, meaning that the cleat will always be forced to point away from theboom and towards the helm ensuring the rope is to hand.
