Use this guide to read the label on your spring tube and identify the correct wire size. Not sure? Email us — we’ll help you select the right replacement springs.
How to Guide
Most spring tube labels only list one spring part number — even if there are two springs inside. If you do not have both part numbers, please use the Wire Size or Door Weight method instead, or email us for assistance.

Follow these steps to order by door weight and take a look at the label reading guide below. Not sure? Email us — be sure to send pictures of the label on your spring tube and we will help you select the correct replacements.
*Important: Check if You Have One or Two Springs (50–110 lb Doors)*
Garage doors that weigh between 50 and 110 lbs can have either one spring or two springs. Look at the label on your spring tube to find out which setup you have:
- If the label shows two spring sizes — one marked RH (right-hand) and one marked LH (left-hand) — your door has two springs.
- If the label shows only one spring size, your door has one spring.
- Quick visual check: Two-spring systems have winding cones and gears on both ends of the tube. One-spring systems have the winding gear and cone only on the right side. The left side will either have a plain cone sticking out with no gears or an idler bracket.
