Dual arm standard height mainsheet jammer. Designed for use on both dinghies and keelboats which require a central jammer for the mainsheet and a central control line, such as the vang, to be easily accessible for the mainsheet trimmer. The dual arm standard height mainsheet jammer is available with or without a 60m Pro-Ratchet Block.Featuring our cold forged bearing system which has a ball-locating groove for smooth rotation, whilst preventing the lateral movement of the arm.The arm can be set to rotate at 180, 220 or 360 degrees by adjusting the stopper pins on the underside of the arm.The jammer arm angles has been carefully optimised to ensure easy cleating and uncleating of both lines. Includes a medium aluminium cam cleat with mega pro-lead on the main arm and a small aluminium cam cleat with mega pro-lead on the lower arm. The lower arm also features two sheaves to help run rope from the middle of the base into the lower cleat.
