Sliding Glass Door Adjustment Screws

Use the screwdriver to adjust this first screw.

Sliding glass door adjustment screws.

If the door becomes even harder to open turn the screw in the opposite direction. To check the adjustment stand back and look at the door from the outside. 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. 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.

Give the screw a clockwise turn and test to see whether the door slides easier. Raise it just enough to clear the track and roll smoothly. Turning the screw clockwise will cause the sliding screen door to become higher as the wheels lower. Turning this screw raises or lowers the roller.

All it takes is a few turns of the adjusting screw on the edge of the bottom rail of the door. As the adjustment screw turns the door either raises or lowers with the rollers allowing for a proper position of the door in the track. Turning the screw counterclockwise raises the wheels on the sliding screen door. Turn the screw counterclockwise to lower the panel if the door is rubbing against the top track.

Tinker around with the roller screws to see if the door glides better when it s at a lower or higher height. Locate the two adjusting screws at the bottom of the door on the face or edge of the door and pry off the trim caps that cover the screws. They may be covered by plug covers if your screws are covered by plug covers use a putty knife to remove them. Sliding doors slide best when a uniform gap is maintained along the edges and bottom of the door.

Take a peek inside the slots at the screws to see whether you need a flat head or phillips head screwdriver. There should be a uniform gap along the bottom and top edges of the door. After a bit of adjustment the door should roll easily without rubbing on the bottom track. Most sliding doors have a mechanism called an adjusting screw located at the bottom of the door ends.

Locate the first screw on the sliding screen door wheel assembly. 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. Turn the screw clockwise with a phillips head screwdriver to lift the door panel off of the lower track if the door is rubbing against the lower track. First locate the screws on the bottom of your sliding glass doors.

Next to lower the sliding glass door use a screwdriver to turn the screws clockwise. If the side with the adjusting screw is too high causing it to bind at the top turn the screw counterclockwise.
