    Installation Tips

    Product details by manufacturer

    Testing Before Installation

    Please note: Testing and operating the gearbox before installing it to the rail can cause the deadbolt (highlighted in red) to become stuck.

    This is because the deadbolt is not being held in place by the rail.

    If this happens cycle the gearbox to the locked position so that the deadbolt sticks out. Hold the deadbolt level, then cycle the gearbox into the unlocked position to retract the deadbolt.

    Once installed this issue will not occur.

    Installation

    1. Remove three screws holding the gearbox onto the rail. The gearbox will then come away from the rail.
    2. Position the rear connector arms on to the connectors inside the gearbox as shown in the image. Once these connectors are correctly aligned the rail should sit flush with the gearbox.
    3. Re-insert and tighten the screws.
    4. Test the door lock to ensure the latch, deadbolt and locking points on the rail all operate correctly.

    After Installation

    It's important to maintain your new gearbox to ensure it lasts. You should periodically lubricate the gearbox and ensure it is clear from dirt and debris.

    Important note: You should consider why your original gearbox may have broken. For example, your door could be out of alignment which puts more force on your gearbox causing it to wear out much faster. This issue may still be present and will cause you new gearbox to wear quickly if it is not rectified.
