Allen Compact Mainsheet Jammer Base with Ratchet

Allen have spent many hours of research and development with various boatbuilders to perfect the angle and height of the cleat to optimize mainsheet jamming.

Designed for use on both dinghies and keelboats which require a central jammer that takes up less space and has a lower cleat. 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 angle has been carefully optimised to ensure easy cleating and uncleating when required.
Includes an aluminium cam cleat with mega pro-lead.

• innovative light weight construction
• dual ball race for maximum efficiency
• optional click stops limit swivel rotation
• line snags virtually elminated
• standard and high cleating angles to suit all.
