Measure Garage Door Springs
(Inside Diameter is taken at the break or Indicated on Stationary Cone)
(Only measure your broken or unwound torsion springs)
1. Determine Length of spring(s) from coil to coil. (Don't measure silver end cones) If you have two torsion springs installed on your garage door, take notice of your wound spring. Most garage doors are installed with a matching set of springs for optimal balance and cycle life, although some companies will install unmatched pairs to limit inventory. Wound or tensioned torsion springs are roughly 2" longer than broken springs due to the turns applied. If the wound or tensioned spring appears to be longer or than 2" or the same length as the broken spring, you may have an unmatched pair. If this is the case you need to deduct 1 coil for every foot of door height. For instance if your garage door is a typical residential garage door, it may be 7 or 8' tall. Please measure the door height, then subtract 1 coil for every foot. Example: If your wound spring measures 25" and your door height is 7' tall, then simply subtract 7 coils from your garage spring. If 8' tall then subtract 8 coils. We would like you to call us if you have any questions or concerns. Toll Free 855-DIY-Garage
2. Determine Coil Diameter: Measure the length of 10 and 20 coils close to the break of the spring to insure accurate tight coils. Follow the chart below to determine correct wire diameter. Extra measurements: Please count all the coils of your broken spring from end to end. We will ask for this during checkout/ordering. Also take a quick measurement of your garage door height. With these extra measurements we are able to insure a proper spring match.
3. Determine Inside Diameter: You have two silver cones on your spring(s) The cone that is mounted near the center has numbers etched or embossed on the outer edge. ie. 175 =1.75" - 200 = 2" - 225 = 2-1/4" - 268 = 2-5/8" etc Indicates Inside Diameter or I.D.
4. Winding: Typically torsion springs are mounted right above the door opening to a center plate or anchor plate. From the inside looking out to the drive or street. Torsion spring mounted on the Right side of center plate is a Left Winding, while the torsion spring mounted on the Left of center is a Right Winding. In some cases on older doors, the torsion springs are mounted on the far right and left near the cable drums. In this case the spring(s) are Right wind on the right and Left wind on the left. As mentioned this is uncommon and only on older garage doors.
Note: The end of the coil near the silver cones are pointed up towards the ceiling.
