A new line of stay tensioning cylinders supplied with a mechanical lock. They allow for the hydraulic pressure release, while keeping the stay under tension mechanically: fundamental for maximum safety when sailing for long distances. Useful for the control of forestays during races, thanks to their simple and quick adjustment system with ring nut.
The cylinders are supplied with pressure rod release. This pressure is charged through the “pneumatic” valve located on the cylinder body, opposite to the rod. Gas pressure should be regulated depending on the release speed you wish. Pressure is charged at 100 psi (7.0 bar) approximately.
Upon request we may manufacture fork-shaped lower fittings.
