The cylinder features a built-in, single-acting pump.\u003cbr\u003e\nEvery 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 indicator attached to the top clevis pin slides down the cylinder as itÕs retracted for repeatable tension settings. Standard eye-jaw toggles fit all  Harken cylinders and are recommended on all installations. 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 9 - 18 m (30 - 60') with stay diameters of 5 - 10 mm (7\/32 - 3\/8\").\u003c\/p\u003e","brand":"Harken","offers":[{"title":"Default Title","offer_id":46963833078069,"sku":"HAR-HCI017BCC","price":2789.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0779\/0392\/1461\/files\/HAR-HCI017BCC.webp?v=1700592335","url":"https:\/\/senditsailing.com\/products\/harken-single-acting-integral-backstay-adjuster-17","provider":"SendIt Sailing","version":"1.0","type":"link"}
