{"product_id":"pair-of-21-x-36-extension-springs-for-6-doors-open-loop","title":"Pair of 21” x 36” Extension Springs for 6’ Doors – Open Loop","description":"\u003cp\u003eExtension springs for 6-foot doors, 21 by 36 inches, with open loop 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":54815001870663,"sku":"EXTSPR2136U","price":43.0,"currency_code":"USD","in_stock":true},{"title":"50 lbs - Red","offer_id":54815001903431,"sku":"EXTSPR2136U1","price":46.0,"currency_code":"USD","in_stock":true},{"title":"60 lbs - Brown","offer_id":54815001936199,"sku":"EXTSPR2136U2","price":50.0,"currency_code":"USD","in_stock":true},{"title":"70 lbs - Orange","offer_id":54815001968967,"sku":"EXTSPR2136U3","price":53.0,"currency_code":"USD","in_stock":true},{"title":"80 lbs - Gold","offer_id":54815002001735,"sku":"EXTSPR2136U4","price":57.0,"currency_code":"USD","in_stock":true},{"title":"90 lbs - Light Blue","offer_id":54815002034503,"sku":"EXTSPR2136U5","price":60.0,"currency_code":"USD","in_stock":true},{"title":"100 lbs - TAN","offer_id":54815002067271,"sku":"EXTSPR2136U6","price":63.0,"currency_code":"USD","in_stock":true},{"title":"110 lbs - White","offer_id":54815002100039,"sku":"EXTSPR2136U7","price":67.0,"currency_code":"USD","in_stock":true},{"title":"120 lbs - Green","offer_id":54815002132807,"sku":"EXTSPR2136U8","price":72.0,"currency_code":"USD","in_stock":true},{"title":"130 lbs - Yellow","offer_id":54815002165575,"sku":"EXTSPR2136U9","price":78.0,"currency_code":"USD","in_stock":true},{"title":"140 lbs - Blue","offer_id":54815002198343,"sku":"EXTSPR2136U10","price":83.0,"currency_code":"USD","in_stock":true},{"title":"150 lbs - Red","offer_id":54815002231111,"sku":"EXTSPR2136U11","price":87.0,"currency_code":"USD","in_stock":true},{"title":"160 lbs - Brown","offer_id":54815002263879,"sku":"EXTSPR2136U12","price":90.0,"currency_code":"USD","in_stock":true},{"title":"170 lbs - Orange","offer_id":54815002296647,"sku":"EXTSPR2136U13","price":98.0,"currency_code":"USD","in_stock":true},{"title":"180 lbs - Gold","offer_id":54815002329415,"sku":"EXTSPR2136U14","price":103.0,"currency_code":"USD","in_stock":true},{"title":"190 lbs - Light Blue","offer_id":54815002362183,"sku":"EXTSPR2136U15","price":110.0,"currency_code":"USD","in_stock":true},{"title":"200 lbs - Tan","offer_id":54815002394951,"sku":"EXTSPR2136U16","price":118.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0910\/9205\/8439\/files\/bestgaragedoorparts11_41.webp?v=1773076720","url":"https:\/\/bestgaragedoorparts.com\/products\/pair-of-21-x-36-extension-springs-for-6-doors-open-loop","provider":"Best Garage Door Parts","version":"1.0","type":"link"}
