Standard height mainsheet jammer

Designed for use on both dinghies and keelboats which require a central jammer.

The 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 angle has been carefully optimised to ensure easy cleating and uncleating when required.

Includes an aluminium cam cleat with mega pro-lead.
