Allen Aluminium Arm Mainsheet Swivel Jammer complete with Ratchet Block
Allen Brothers A5166 Aluminium arm mainsheet swivel jammer supplied with an Allen A2160 60mm Pro-Ratchet Block suits large dinghies and the 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.
Allen's design team spent many hours of research and development improving the range of their aluminium mainsheet jammers.
