DASMA

DASMA stands for the Door & Access Systems Manufacturers Association. This is the organization responsible for developing the guidelines and specifications for garage door spring color codes. The color codes are supplemental aids to help identify the correct springs. Because springs all look so similar, the codes help consumers find the right springs and they help retailers keep products organized ensuring the right spring gets to the customer.

Understand How To Choose The Right Springs Without Color Codes

Not all springs have visible color codes, if you can’t see the color on the springs that will be removed you’ll want to know how to choose the right springs by measurements. Take the measurements to a garage door professional and they’ll help you find the right spring.

Extension Springs

Measurements you’ll want to note include:

Height of the door
Extension springs vary in length. Springs that work for a standard height door won’t work for an extra tall door because the springs will need to extend farther.

Weight of the door
The weight of the door can be difficult to calculate but it’s a crucial measurement because the springs need to counterbalance the weight to function properly.

Torsion Springs

Measurements you’ll want to note include:

In addition to having the weight and height of the door recorded, torsion springs need additional measurements for replacement.

Length
Measure the spring from the first to the last coil.
Wire Size
Measure the thickness of the wire in the spring. To measure wire size, insert the tape measure between the first two coils and stretch it to the last coil between the 10th and 11th coils.
Spring Wind
Left wind springs are located on the right-hand side of the door and right wind springs are located on the left side.
Inner Diameter
Measure the diameter of 1/16” of an inch. Sometimes this number is written on the winding or stationary cone. If you see a 1.75 on the cone the spring has a 13/4-inch diameter.

The Wrong Size Spring Can Cause Serious Problems

A door that is too large or too small can:

Damage the opener
Wear down the cables
Cause a safety hazard
Damage the garage door
