RWO's Lance Cleat is like a rugged miniature drum mounted alongside a single cam and mounted vertically in a black-molded, reinforced stainless steel frame. Rather than lifting the line out of the cam, the trimmer would slide it to the left or the right to release it from the cam. Lance Cleats are available with the roller on the left and the cam on the right for starboard side applications and vice versa for port side applications. R3597 works with 7/64 in (3mm) to in (6mm) line and cleats to port. R3598 works with 7/64 in (3mm) to in (6mm) line and cleats to starboard. Mast mounting below the spinnaker halyard exit allows you to hoist from the mast and cleat it off temporarily. Mounting it just off center of where the spinnaker halyard leads down the side of the mast allows the halyard to uncleat its self when it is later tensioned and cleated off from the cockpit.
