{"product_id":"pair-of-21-x-36-extension-springs-for-6-doors-closed-loop","title":"Pair of 21” x 36” Extension Springs for 6’ Doors – Closed Loop","description":"\u003cp\u003eExtension springs for 6-foot doors, 21 by 36 inches, with double ends and S-hooks. The S-hooks connect the spring between the rear stationary bracket and the pulley\/safety cable assembly. This set covers door weights from 40 to 200 pounds, and you pick the right rating from the dropdown. That's a wide range, so don't just guess your door weight. If you've got the old springs, check if there's a code stamped on them that indicates the lift rating. Replace as a pair even if only one spring is stretched out. Both will be fatigued at the same rate.\u003c\/p\u003e","brand":"Best Garage Door Parts","offers":[{"title":"40 lbs - Blue","offer_id":54764448481607,"sku":"EXTSPRUSA2136","price":45.0,"currency_code":"USD","in_stock":true},{"title":"50 lbs - Red","offer_id":54764448514375,"sku":"EXTSPRUSA21361","price":48.0,"currency_code":"USD","in_stock":true},{"title":"60 lbs - Brown","offer_id":54764448547143,"sku":"EXTSPRUSA21362","price":53.0,"currency_code":"USD","in_stock":true},{"title":"70 lbs - Orange","offer_id":54764448579911,"sku":"EXTSPRUSA21363","price":55.0,"currency_code":"USD","in_stock":true},{"title":"80 lbs - Gold","offer_id":54764448612679,"sku":"EXTSPRUSA21364","price":59.0,"currency_code":"USD","in_stock":true},{"title":"90 lbs - Light Blue","offer_id":54764448645447,"sku":"EXTSPRUSA21365","price":62.0,"currency_code":"USD","in_stock":true},{"title":"100 lbs - TAN","offer_id":54764448678215,"sku":"EXTSPRUSA21366","price":65.0,"currency_code":"USD","in_stock":true},{"title":"110 lbs - White","offer_id":54764448710983,"sku":"EXTSPRUSA21367","price":70.0,"currency_code":"USD","in_stock":true},{"title":"120 lbs - Green","offer_id":54764448743751,"sku":"EXTSPRUSA21368","price":75.0,"currency_code":"USD","in_stock":true},{"title":"130 lbs - Yellow","offer_id":54764448776519,"sku":"EXTSPRUSA21369","price":80.0,"currency_code":"USD","in_stock":true},{"title":"140 lbs - Blue","offer_id":54764448809287,"sku":"EXTSPRUSA213610","price":85.0,"currency_code":"USD","in_stock":true},{"title":"150 lbs - Red","offer_id":54764448842055,"sku":"EXTSPRUSA213611","price":89.0,"currency_code":"USD","in_stock":true},{"title":"160 lbs - Brown","offer_id":54764448874823,"sku":"EXTSPRUSA213612","price":93.0,"currency_code":"USD","in_stock":true},{"title":"170 lbs - Orange","offer_id":54764448907591,"sku":"EXTSPRUSA213613","price":100.0,"currency_code":"USD","in_stock":true},{"title":"180 lbs - Gold","offer_id":54764448940359,"sku":"EXTSPRUSA213614","price":105.0,"currency_code":"USD","in_stock":true},{"title":"190 lbs - Light Blue","offer_id":54764448973127,"sku":"EXTSPRUSA213615","price":112.0,"currency_code":"USD","in_stock":true},{"title":"200 lbs - Tan","offer_id":54764449005895,"sku":"EXTSPRUSA213616","price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0910\/9205\/8439\/files\/bestgaragedoorparts11_71.webp?v=1774545360","url":"https:\/\/bestgaragedoorparts.com\/products\/pair-of-21-x-36-extension-springs-for-6-doors-closed-loop","provider":"Best Garage Door Parts","version":"1.0","type":"link"}
