DASMA Color Codes for Garage Door Springs

When you look closely at garage door torsion or extension springs, you’ve likely noticed the colorful paint that is used to differentiate springs in the overhead door industry. DASMA (Door & Access Systems Manufacturers Association) has created the industry standard for color coding springs.  

To help you understand the DASMA color coding, here’s what you need to know:

What kind of garage door spring do you have?

The first step in figuring out what the spring color coding means is to know the type of garage door spring. The majority of garage doors use torsion springs, a wound spring that when twisted will exert torque to help lift the garage door. These springs are generally installed above a garage door. Used less often, extension springs create energy through a pulling force. Extension springs are generally installed on the sides of garage doors.

Torsion springs will generally have two different colors. First, each spring will be marked with red or black. Red springs are ‘right-wound springs’ while black springs are ‘left-wound springs’. The other color on the torsion spring is the DASMA color. The color signifies the wire size or wire gauge. Color does not signify which side of the door the spring is installed on.

Pro Tip: Always confirm the wire size of a torsion spring using a spring wire gauge, pocket wire gauge or the wire size formula. Click here to learn how to find the wire size of a torsion spring.

DASMA Color Code Chart for Garage Door Extension Springs

The color coding of an extension spring refers to the garage door weight that two extension springs are capable of lifting. So for example a green extension spring would be capable of lifting 20#, 120#, or 220#. Because there are only 10 unique colors, the colors repeat for light weight or extra heavy garage doors.

Pro Tip: When ordering garage door extension springs, make sure to specify the weight/pull of the spring you need as well as the color. This will help to eliminate a misunderstanding of weight capacity since the color code is repeated. For example, say White, 110# Extension Spring)
