{"product_id":"commercial-torsion-spring-0-406-wire-size-left-hand-wind","title":"Commercial Torsion Spring 0.406 Wire Size - Left Hand Wind","description":"\u003cp\u003eCommercial torsion springs available in 2-5\/8\" and 3-3\/4\" inside diameter. Made from oil-tempered steel for high-cycle commercial doors, the kind you see on warehouses, loading docks, and service bays that open and close dozens of times a day. The dual cone design keeps the spring centered on the shaft so tension stays even. These aren't residential springs, they're heavier and wound differently. You'll need your exact spring specs to order the right one: wire size, length, inside diameter, and whether it's left or right wound. Getting those numbers wrong means the door won't balance. \u003cstrong\u003eBore size option of 1.25\" is available only for 3-3\/4\" inside diameter, that is why picking 1.25\" option with 2-5\/8\" will result in variation reset.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Best Garage Door Parts","offers":[{"title":"2-5\/8\" \/ 36\" \/
