{"title":"Commercial Torsion Springs","description":"\u003cp\u003eTorsion springs sit on a shaft above the door and do the heavy lifting — literally. The stored torque in the coils is what raises and lowers a door that might weigh a few hundred pounds. All ours are oil-tempered USA steel. To get the right replacement you need four things: wire size (calipers or count 10 and 20 coils), inside diameter, coil length without the cones, and wind direction. Left-wound goes on the right side of the bracket. Replace both springs, always, and use real winding bars.\u003c\/p\u003e","products":[{"product_id":"commercial-garage-door-torsion-springs-2-5-8-and-3-3-4-copy","title":"Commercial Torsion Spring 0.243 Wire Size","description":"\u003cp\u003eCommercial torsion spring available in 2-5\/8\" inside diameter.

Torsion Spring 0.283 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\"

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\"

Torsion Spring 0.319 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\"

Torsion Spring 0.362 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\"

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\"

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\"

Torsion Spring 0.362 Wire Size - Right 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\"

Torsion Spring 0.343 Wire Size - Right 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\"

Torsion Spring 0.312 Wire Size - Right 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\"

Torsion Spring 0.283 Wire Size - Right 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\"

Torsion Spring 0.273 Wire Size - Right 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\"

Torsion Spring 0.262 Wire Size - Right 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\" \/ 34\" \/
