Standard height self aligning mainsheet jammer.

Our self aligning mainsheet jammer is the only one of its type available on the market. It offers hands-free turning of the jammer through tacks and gybes.

The self aligning jammer works by having the ratchet block set off to one side.

By moving the block outward from the swivel and angling it away from the cleat, the A5266 mainsheet system creates turning force on the block and jammer meaning the cleat will always be forced to point away from the leeward side of the boat.

This prevents the sheet from wrapping around the block and gives extra control for fast, smooth tacks and gybes.

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.
