{"product_id":"single-acting-integral-backstay-adjuster","title":"Single-Acting Integral Backstay Adjuster","description":"\u003cp\u003e Harken's 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. \u003cbr\u003eEach 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 it is 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":"10","offer_id":47110392611003,"sku":"HCI010BCC","price":28539.0,"currency_code":"NOK","in_stock":true},{"title":"12","offer_id":47110392676539,"sku":"HCI012BCC","price":31289.0,"currency_code":"NOK","in_stock":true},{"title":"17","offer_id":47110392709307,"sku":"HCI017BCC","price":31289.0,"currency_code":"NOK","in_stock":true},{"title":"6","offer_id":47110392774843,"sku":"HCI006BCC","price":28539.0,"currency_code":"NOK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0543\/6607\/7115\/files\/uc_1e6ac6bd-54b6-44a6-8c0d-48baa9c0d197.jpg?v=1769940917","url":"https:\/\/hovdan.no\/en\/products\/single-acting-integral-backstay-adjuster","provider":"Hovdan industri- og båtutstyr","version":"1.0","type":"link"}
