About Splicing your Spring.

Splicing springs is a technique that installers have been doing for years, this has been done on everything from small residential garage doors to heavy commercial garage doors and always temporarily fixes the problem. Splicing garage door springs is only temporary, It is only a matter of time before another coil on the spring breaks, After this repair your garage door should operate normally. It is highly recommended that you replace your garage door spring to prevent problems with the spring breaking again trapping your vehicle inside, falling on your vehicle or worse, hurting someone.

The photos in this instruction page use a spring that is not assembled on a garage door, Usually this is done while the spring is assembled on the garage door (the process is the same).


This page was written by Pro Door Supply for instructional purposes only, garage door springs are under high amounts of pressure and can cause serious injury if not handled properly. Pro Door Supply accepts no responsibility of personal injury based on this information, you should consider your own abilities before doing this project.



Part 1: Splicing the Garage Door Spring

Spring Clip

Step 1. First, disassemble the spring clip. Then pry one coil from the broken side of the spring. after you have done that place the coil inside the "U" part of the clip (place the "U" a few inches from the end of the coil).

Step 2. Repeat the Process for the other half of the broken spring. Placing one coil from each side in the "U".

Step 3. Assemble the clip, and tighen the clip evenly. Make sure this is tight, if it is not tight the coils will slip out while you are winding the spring.

Part 2: Winding the Garage Door Spring

There are two scenarios that are involved here; either a 1 spring system or a 2 spring system. On a 2 spring system skip to step 3.

Step 1. Make sure the garage door cables are in the right place. If you have one spring on your garage door, there is a good chance that they fell off the drum when the spring broke.

Step 2. loosen the cable drums on both sides of the garage door (7/16" wrench), and replace the cable into the slot on the cable drum. Start with the left hand side (red) of the door, rotate the cable drum until the cable is tight, then tighten the set screws. Hold the drum in place, and lock the shaft with the vice grips (locking plyers).


After you have the left side tight, repeat the process for the right side, this time you will not have to lock down the shaft. It should look like this when you are done.

Step 3. Putting Tension back on the garage door spring. Insert the winding bar into one of the 4 holes on the winding cone, and add tension 1/4 turn at a time. For 7' tall garage doors roughly 7 1/2 full turns, for 8' garage doors roughly 8 1/2 full turns.
