Choosing the correct garage door torsion spring is important for safe, smooth, and reliable garage door operation. If your garage door spring is broken, worn out, or needs to be replaced, the first step is identifying the correct replacement spring.

This guide explains how to find the right EZ-SET® torsion spring using simple measurements from your old spring, your garage door size, or your door weight.

Important Safety Note: Garage door springs are under extreme tension. Measuring a spring can be done carefully, but installation or replacement should be handled by a trained garage door professional if you are not experienced.

What Is an EZ-SET® Torsion Spring?

An EZ-SET® torsion spring is a specific style of garage door spring used on certain garage door systems. These springs help lift and balance the garage door so the opener and hardware do not have to carry the full weight of the door. EZ-Sets exclusively uses Clopay Winding Units and Clopay Ez-Set Drums. 

When replacing one EZ-SET® torsion spring, it is important to match the spring correctly. Using the wrong spring can cause the door to be too heavy, too light, uneven, unsafe, or difficult to operate.

The EZ-SET® spring guide gives customers three ways to identify the correct spring:

1. Measure the old spring
2. Select by door height and weight
3. Select by door model and size

Option 1: Find Your EZ-SET® Spring by Measuring the Old Spring

The most accurate way to identify your replacement spring is to measure the spring that is already on your garage door.

You will need to measure:

• Wire diameter
• Inside diameter (Always 1.75 in.)
• Coil length
• Wind direction

Step 1: Measure the Wire Diameter

To find the wire diameter, measure 10 coils tightly together.

For example, if 10 coils measure 1-15/16 inches, that equals about 1.92 inches. Then move the decimal point one place to the left, giving you a wire diameter of .192.

Common EZ-SET® wire diameters include:

This measurement is important because even a small difference in wire size can change how much weight the spring can lift.

EZ-SET® Spring Color Codes

EZ-SET® torsion springs often use color codes to help identify the spring size. Common spring color categories include: 

These colors help narrow down your spring, but you should still confirm the measurements before ordering. 

(Note: Some times spring may show two colors one near the winding cone end of the spring, and the other near the tail/attachment end. the tail end may usually be green or black to indicate the wind direction. It is imperative to follow the measurement to double check your wire size.)

Step 2: Inside Diameter

Clopay EZ-set springs come only in standard 1.75" (1-3/4") inside diameter and will always remain the same.

Step 3: Measure the Coil Length

Measure the length of the spring coils only.

Do not include the end cones or hardware. Measure only the coiled section of the spring.

Common coil lengths include sizes such as:

• 28"
• 32"
• 36"
• 42"
• 47"
• 50"
• 53"
• 58"
• 62"
• 66"
• 71"

The spring length helps identify whether your spring is a Gold, Orange, Yellow, White, Red, Brown, or Green EZ-SET® spring. 

Step 4: Determine the Wind Direction

EZ-SET® torsion springs come in two wind directions:

• Left wound spring, often marked as LW
• Right wound spring, often marked as RW

The wind direction matters. A left-wound spring and right-wound spring are not interchangeable.

When shopping for your replacement spring, check whether your old spring is labeled LW or RW, or compare the spring coil direction to a spring wind direction chart.

For EZ-Set Springs only: If you are standing on the inside of the garage looking out to the driveway. The Left hand spring will be LEFT Wind, and vice versa,

Option 2: Find Your Spring by Door Height and Door Weight

Another way to select an EZ-SET® torsion spring is by using the height and weight of your garage door.

The guide separates spring options for:

• 7-foot tall garage doors
• 8-foot tall garage doors

For example, certain 7-foot doors may use one left-wound spring only, while heavier doors may require a left-wound and right-wound spring combination.

7' Tall Garage Doors

8' Tall Garage Doors

This method is helpful if the original spring is missing, damaged, or unreadable.

Option 3: Find Your Spring by Door Model and Size

The third method is to identify the correct spring using your garage door model and size.

This is a useful method if you know your door model, size, and insulation type.

Should You Replace One Spring or Both Springs?

If your garage door uses more than one spring, it is usually best to replace all springs on the door at the same time.

The EZ-SET® guide specifically notes that if you are replacing one spring, you should replace all springs on the door. This helps keep the door balanced and prevents one older spring from failing shortly after the new one is installed.
