Double-pull cylinders have rods on both ends and are used with mainsheet travelers or jib sheet car systems to easily adjust loaded sails. As oil is pumped into the cylinder, the rod pulls the traveler while the other rod eases. Reverse the process and the eased rod pulls the other way. Delrin® isolaters separate the cylinders from the metal elements of the hull to prevent corrosion.

What makes Harken® double-pull cylinders unique is the way they are installed on the boat. To take the cylinder off the mounting brackets for service, the user simply removes four screws, leaving both brackets in place.

Double-pull cylinders do not come with end fittings on the rod because of the variety of cylinder functions. Harken has a selection of end fittings to choose from. Fittings are sold separately.
