Torsion Springs

Garage Door Torsion Spring Chart We carry garage door torsion springs in a variety of sizes and materials. Torsion springs account for over 95% of the lift that is needed to raise a garage door. Because of this continual stress, torsion springs typically only last for 12,000- 15,000 cycles. We offer torsion spring replacement and installation services.

To make the process faster for ordering torsion springs follow the instructions below to provide the correct measurements.

  1. Measure the inside diameter. The best way to do this is to examine the end cone. Most cones will be printed with a number identifying the inside diameter on the opposite side of the manufacturing code, such as DNS 175, which designates a 1.75 inch diameter, or P200W, designating a 2 inch diameter. Many heavier residential garage doors use springs with 2 ⅝ inside diameters.
  2. Identify the length and wire size. Usually, springs have a metal tag that identifies the length and wire size, such as 225-22BR. The 225 is the wire size and 22 is the length in inches. The R designates that it’s a right-wind spring.
  3. If there is no tag designating the length, measure the entire length of the spring. If it’s broken, measure each piece.
  4. To measure the wire size, count and mark 10 and 20 coils with small pieces of paper. Measure both sets of 10 coils, then measure all 20 coils together. If the 20-coil measurement isn’t exactly twice the 10-coil measurement, re-measure each 10-coil segment.
  5. Determine whether it’s right-hand or left-hand-wound. The direction of the wind on the spring is opposite the side that it goes on, so the left-wound spring is installed on the right hand side of the door, as you’re standing inside your garage looking out. Often, the right-wound springs are marked with red paint, and left-wound springs are marked with black paint.
