How To: Adjust Sliding Glass Door Rollers

Tools required: Screwdriver, putty knife, safety glasses and gloves.

This is how to adjust the door's rollers to ensure smooth operation and maintain weather tightness..First thing, check your wheels. There are two adjustments on the door panel covered by plug covers. Using a stiff putty knife, remove the plug covers. The screw ports allow access to Philips head screws to raise and adjust the door.

When you need to raise the door, place the putty knife under the door and push the door upwards. This takes pressure off the wheel. To raise the door, turn the screw clockwise. To lower the door, turn the screw counterclockwise.

Whenever you adjust one side, you must adjust the other side accordingly. To tell if there is an even reveal, slide the door towards the door jam and line it up to make sure the gap is even from top to bottom.

Insert the plugs once you have adjusted the door and it is sliding properly.
