{"product_id":"zipcrank-height-adjusters","title":"Bison ZipCrank Height Adjusters","description":"\u003cp\u003eTransition from adult to youth play in about a minute with ZipCrank corner-mount rim height adjusters, engineered to maintain backboard and rim rigidity unlike many traditional adjustable goal systems. The movable framework travels vertically on two chrome-plated 1\" diameter rods guided by machined steel bushings for smooth, stable operation.\u003c\/p\u003e\n\u003cp\u003eInstalled between the backboard and its support structure, retrofit applications will move the face of the backboard approximately 4¼\" toward the free-throw line and may require minor field drilling on some existing systems. The adjuster provides infinite rim height adjustment from the regulation 10' down to 8' and includes easy-to-read height indicator labels. Operation is via the included hand crank or the optional BA931 Cordless Winch Winder.\u003c\/p\u003e\n\u003cp\u003eRim height adjusters are not warranted for adult dunking or hanging. Refer to the ordering chart for model selection, including applications on center-strut structures. Backed by a five-year limited warranty.\u003cbr\u003e\u003c\/p\u003e","brand":"Bison","offers":[{"title":"Fan Shaped","offer_id":51054716322070,"sku":"BA980F","price":1887.0,"currency_code":"USD","in_stock":true},{"title":"48'' x 72''","offer_id":51054716354838,"sku":"BA980RT","price":2109.0,"currency_code":"USD","in_stock":true},{"title":"42'' x 72''","offer_id":51054716387606,"sku":"BA980RS","price":2035.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/0029\/5702\/files\/Height-adjusters.jpg?v=1771866597","url":"https:\/\/proathleticsupply.com\/products\/zipcrank-height-adjusters","provider":"Pro Athletic Supply","version":"1.0","type":"link"}
