Sliding Glass Door Height Adjustment
If it s too low use a flat pry bar to raise the door while you turn the adjusting screw clockwise.
Sliding glass door height adjustment. Locate the first screw on the sliding screen door wheel assembly. This adjustment screw will move the roller height up or down and thus your sliding glass door height will go up or down by as much as 1 4 inch or 1 2 cm. They may be covered by plug covers if your screws are covered by plug covers use a putty knife to remove them. Take a peek inside the slots at the screws to see whether you need a flat head or phillips head screwdriver.
If the side with the adjusting screw is too high causing it to bind at the top turn the screw counterclockwise. Once you have found or gained access to the adjustable screws on the wheel assembly you can then begin the process of adjusting the sliding screen door s height. Open your door approximately six inches and watch the gap between the door and frame turn the adjustment screws with your screwdriver until a uniform gap is achieved. Regular vacuuming of the track will help keep the door sliding smoothly.
Next to lower the sliding glass door use a screwdriver to turn the screws clockwise. Tinker around with the roller screws to see if the door glides better when it s at a lower or higher height. Once you ve adjusted your door slide it back and forth a few times in the track to make sure it s working properly. You may only need to adjust one of the screws to get your door back on track or you might have to tinker with both sets.
If there s still some resistance try loosening further.
