{"product_id":"21x36-ext-spring-pair-6ft-closed-loop","title":"Garage Door Extension Springs Pair 21x36 for 6 ft Door, Closed Loop","description":"\u003cp\u003eThis pair of 21 by 36 inch extension springs is made for 6-foot garage doors with closed loop ends. Choose the door weight option that matches the actual weight of your door so the springs can balance the door correctly. The closed loop end style is made for standard extension spring hardware and helps keep the connection stable during normal door travel. These springs are intended for doors that already use an extension spring system, and replacing both sides as a pair helps the door move more evenly.\u003c\/p\u003e","brand":"SuplinkTechCorp","offers":[{"title":"40 lbs - Blue","offer_id":50175594004618,"sku":"STC-EXT-2136-06-CLS-040","price":45.0,"currency_code":"USD","in_stock":true},{"title":"50 lbs - Red","offer_id":50175594037386,"sku":"STC-EXT-2136-06-CLS-050","price":48.0,"currency_code":"USD","in_stock":true},{"title":"60 lbs - Brown","offer_id":50175594070154,"sku":"STC-EXT-2136-06-CLS-060","price":53.0,"currency_code":"USD","in_stock":true},{"title":"70 lbs - Orange","offer_id":50175594102922,"sku":"STC-EXT-2136-06-CLS-070","price":55.0,"currency_code":"USD","in_stock":true},{"title":"80 lbs - Gold","offer_id":50175594135690,"sku":"STC-EXT-2136-06-CLS-080","price":59.0,"currency_code":"USD","in_stock":true},{"title":"90 lbs - Light Blue","offer_id":50175594168458,"sku":"STC-EXT-2136-06-CLS-090","price":62.0,"currency_code":"USD","in_stock":true},{"title":"100 lbs - TAN","offer_id":50175594201226,"sku":"STC-EXT-2136-06-CLS-100","price":65.0,"currency_code":"USD","in_stock":true},{"title":"110 lbs - White","offer_id":50175594233994,"sku":"STC-EXT-2136-06-CLS-110","price":70.0,"currency_code":"USD","in_stock":true},{"title":"120 lbs - Green","offer_id":50175594266762,"sku":"STC-EXT-2136-06-CLS-120","price":75.0,"currency_code":"USD","in_stock":true},{"title":"130 lbs - Yellow","offer_id":50175594299530,"sku":"STC-EXT-2136-06-CLS-130","price":80.0,"currency_code":"USD","in_stock":true},{"title":"140 lbs - Blue","offer_id":50175594332298,"sku":"STC-EXT-2136-06-CLS-140","price":85.0,"currency_code":"USD","in_stock":true},{"title":"150 lbs - Red","offer_id":50175594365066,"sku":"STC-EXT-2136-06-CLS-150","price":89.0,"currency_code":"USD","in_stock":true},{"title":"160 lbs - Brown","offer_id":50175594397834,"sku":"STC-EXT-2136-06-CLS-160","price":93.0,"currency_code":"USD","in_stock":true},{"title":"170 lbs - Orange","offer_id":50175594430602,"sku":"STC-EXT-2136-06-CLS-170","price":100.0,"currency_code":"USD","in_stock":true},{"title":"180 lbs - Gold","offer_id":50175594463370,"sku":"STC-EXT-2136-06-CLS-180","price":105.0,"currency_code":"USD","in_stock":true},{"title":"190 lbs - Light Blue","offer_id":50175594496138,"sku":"STC-EXT-2136-06-CLS-190","price":112.0,"currency_code":"USD","in_stock":true},{"title":"200 lbs - Tan","offer_id":50175594528906,"sku":"STC-EXT-2136-06-CLS-200","price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/5495\/4122\/files\/STC_019.webp?v=1775683273","url":"https:\/\/suplinktechcorp.com\/products\/21x36-ext-spring-pair-6ft-closed-loop","provider":"Suplink Tech Corp","version":"1.0","type":"link"}
