How to Adjust Garage Door Top Fixtures

Hi I'm Dan Musick in this video we'll show you how to adjust the top fixture roller carrier to seal the gap between the top section and the header and jams. Here's how the hinges and door track work together. The track slants in towards the jam as it approaches the floor. The hinges are graduated so that the lowest roller is closest to the section and the highest rollers furthest. The hinges follow this sequence. If they're not in the correct order numbered from the bottom 1,2,3, and so forth you will not have a consistent gap. First measure the gaps between the door and the jam. You can either measure from the door jam to the outside of the door or from the door jam to the inside of the door. Once you've taken the measurements decrease the gap to 1/4" if your door frame allows for it. To adjust for the gap on the top section you'll need to adjust the top fixture. To do this loosen the nuts that secure the roller carrier to the top fixture this will let the roller slide back and forth and allow you to adjust the top section. To minimize the gap pull out the roller pushing the door forward until you get a consistent gap then tighten the bolts. Before using the opener open the door manually to ensure that the top of the door does not hit the opener rail. One thing that can happen when you adjust the roller carrier is that as you open the door the top of the roller binds in the track. This can cause the hinge to break or wear prematurely. If this happens you need to lower the top fixture on the door positioning it closer to the hinge below it. To do this remove the screws securing the fixture to the door then lower the top fixture an inch or two and secure the screws with a drill or impact wrench. Next adjust and secure the roller carrier, notice that the roller is closer to the section. While this may solve the binding problem it can also create another issue. If your garage does not have enough headroom the top of the door may hit the cable drum. This occurs because by moving the top fixture you've changed the point at which the door pivots. So instead of turning almost immediately when the top of the door hits the curve it travels upwards a little further before turning. If this occurs raise and secure the top fixtures high enough to prevent the top of the door from hitting the open a rail or drums. If you find that you have to relocate the top fixtures to their original positions you have three options. One is to return the rollers to their original positions and replace the top hinges periodically or you can adjust the top roller carriers so there's a bigger gap. This can be remedied by bending the tops at the vertical PVC stop molding to seal the door. A third option is to install low headroom top fixtures or double low headroom tracks and accompanying hardware. You may prefer to have a professional do this for you.
