| Extension Springs Defined: Garage doors are typically balanced either by torsion springs or extension springs. Extension springs are generally mounted just above the horizontal track, perpendicular to the closed garage door. They provide lifting power by stretching (extending). Warning: If an extension spring breaks, broken spring parts can cause injury by flying around the garage. However, a safety cable, installed inside each extension spring, can contain the spring and prevent injury. If you have extension springs but do not have a safety cable, call us for a safety inspection. Only an experienced technician should service garage door springs. |

| The Photo To The Right Is An Example Of A Double Wide Door Extension Spring Installed With The Wrong Size Pulley. The Pulley Is The Wheel Attached To The Spring That The Cable Rides Around. The Pulley Shown Is only 3" In Diameter And Normally Used Only On Single Wide Doors. Normally A 4" Pulley Is Used On A Spring Of This Size. |
| Torsion Springs Defined: Torsion springs are usually mounted above a closed door, parallel and horizontal to the top section of the door. They provide lifting power for the door by winding and unwinding while the door is opened and closed. Warning: The torsion spring is under high tension and requires special tools for adjustment. Because of the high tension, the torsion spring and any part associated with the counterbalance system should be adjusted only by a professional. These parts include: the springs, the cables, the corner brackets attached to the cables, the cable drums, and the center bearing bracket that holds the torsion spring shaft. |

| Balance Test 1. Start With The Door In The Closed Position. 2. Pull The Emergency Disconnect Release Cord. 3. Raise The Door Up 3 to 4 Feet By Hand, Being Sure To Use The Lift Handles And Not The Hinges To Avoid An Injury. (See The Photo Below) If The Door Stays Open On Its Own Without Any Help From You Or The Motor Then The Door Is Balanced. If The Door Springs Open Quickly Then The Springs Are Too Strong And Need To Be Adjusted Or Replaced. If The Door Falls To The Ground Quickly The The Springs Are Too Weak And Need To Be Adjusted Or Replaced. |
