    How to Adjust Garage Door Cable Tension

    In recent years, garage doors have become more convenient and homeowner-friendly in terms of use and repair.

    Hence, it is essential to always be aware of the condition of your garage and garage door system as components can get misplaced, misaligned, or loose.

    Components include brackets, tracks, cables, springs, motors, and more.

    In this article, you will learn how to adjust garage door cable tension.

    What Garage Door Cables Do

    If you’ve noticed, garage doors are massive and are very heavy; thus, the right components are needed to support the weight of the door through its cycle of opening and closing.

    The two components tasked with this important role are the springs and cables.

    Although the spring does most of the heavy lifting, cables play an essential role in supporting the springs and doing one other role.

    Springs build up tension from having to lift the heavy garage door, and the tension can exceed the springs’ limit, causing spring failure.

    In case of a spring failure, the cable intervenes against the spring recoil, which can be quite dangerous, to the point of inflicting death.

    A well-cabled spring will simply fall to the ground during failure; hence, it is essential that the cable is properly installed.

    Adjusting Your Garage Door Cable Tension

    Maintenance is necessary for prolonging your garage and garage door system’s lifespans; thus, regular inspections are necessary to ensure that each component is intact.

    If you notice that your garage door cable might not have the right tension, then it might be time for you to adjust it.

    You don’t have to worry about hiring professional garage door technicians to do this task for you; there’s a way for you to do it safely.

    However, if you feel the need to call for professional assistance, do not hesitate to do so.

    Nevertheless, below are the steps on how to adjust garage door cable tension:

    What You’ll Need

    Before getting to adjusting the garage door cable tension, ensure that you are equipped with the following items:

    • Flathead Screwdriver
    • Pliers
    • Wire-Cutters
    • C-Clamps
    • Stepladder
    • Hard Hat
    • Gloves

    Step 1: Open the Door and Attach the C-Clamps

    Before actually getting to work, wear your hard hat and gloves.

    Then, fully open the door with the opener and, using the stepladder, attach the C-clamps on either side of the tracks closest to the bottom of the door as a safety precaution.

    Opening the door will release the tension in the springs, making the adjustment safer as a closed garage door has the springs under tension.

    Moreover, attaching the C-clamps will ensure that the door won’t suddenly fall while you’re working on adjusting the cable.

    Step 2: Release the Door Opener from the Drive Chain

    To release the door opener from the drive chain, go to the attachment of the opener to the garage door mechanism and look for a rope.

    Pulling this rope should complete this task.

    Step 3: Release the Cable

    Use the stepladder to boost yourself up and have easier access to the cable.

    Disconnect the garage door cable that runs around the door’s frame; one end should wrap around a hook or clip while the other wraps around the rollers.

    Disconnect the end of the cable with the hook from the frame and move it further down using one of the holes below.

    Moving it further down the frame should make the cable tauter.

    Step 4: Adjust the Cable Bracket

    If you find that the cable is still slack and you can no longer hook one end of the cable lower in the frame, then adjust the bracket holding the cable to the frame.

    Using the pliers, loosen the bracket and pull the excess cable until tautness is achieved.

    After, simply retighten the cable bracket and reattach the cable to the frame using the hook.

    Note that you only need to loosen the shaft enough for you to maneuver through it; loosening or tightening it more than necessary can unwind the cables and cause more trouble.

    Step 5: Test Your Garage Door

    Before running your garage door opener through a full cycle, check the cable for any unwinding; the cable should travel around the frame and wrap around the drum neatly.

    After ensuring that everything is aligned, remove the C-clamps on either side of the tracks and plug your opener back into your garage door.

    If nothing is out of place after running your opener through a full cycle, then you’re good to go!
