Allen Mainsheet Jammer

Allen Mainsheet Jammer

Our design team spent many hours of research and development improving the range of aluminium mainsheet jammers.  The A5166 range uses an updated 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.
