b'NEWSingle-Acting Integral Backstay AdjustersHarkens integral hydraulic backstay adjuster provides the power to optimize sail shape quickly for racers and adjust mast tension for smoother furling for cruisers. The cylinder features a built-in, single-acting pump.Every unit includes a hardcoat-anodized aluminum cylinder and pump, valve, and stainless pump handle with two attachment options: 1) a roll pin, that when installed, locks the handle permanently, 2) the roll pin can be left off and the handle may be inserted when needed, but stored separately. Cylinders include a clevis pin on both ends. A fiberglass position marker attached toHarken recommends attaching a the top clevis pin slides down the cylinder as its retracted fortoggle to the cylinders bottom clevis repeatable tension settings. Standard eye-jaw toggles fit allto accommodate stay movement. Harken cylinders and are recommended on all installations. Standard eye-jaw toggles fit all Harken cylinders.The pressure-release knob turns clockwise to close and pump, counterclockwise to release. When closing the pump, the knob cannot be over-tightened by hand, preventing damage to the valve. Release speed depends on how far open the knob is turned. Pressure relief is factory set to prevent crew from over-tensioning the backstay. Harken integral backstay adjusters come in four sizes to fit boats with 5 - 10 mm (7/32 - 3/8") wireapproximately 9 - 18 m (30 - 60\').Supplied fiberglass position marker provides easy visual reference to duplicate desired tension settings.For replacement position marker assembly, order part number H-85275.Wine & Spirits, GS 48, 14.90 m (48.9\')Fabio Taccola / Grand Soleil YachtsMaxPin center lengthGap/pinPart wireStroke (closed)* Weight**Pull force No. - Size in mm in mm in mm lb kg in mm lb kgHCI006BCC-67/325.514.17360307628.363.797/1611.137701710HCI010BCC-109/32714.17360307628.363.791/212.747102130HCI012BCC-125/16814.17360307629.724.415/815.967103040HCI017BCC-173/89.514.17360307629.724.415/815.983903800*For pin center length open (PCLO) add stroke length to pin center length closed. **Rod ends (forks) included in weights.Relief valves are preset to limit max tension (pull force) to recommend rigging loads and cylinder design limits.
