How to Raise a Sliding Glass Door

Adjustment for sliding glass door

Before installing a Lockking Security Lock Bar you should raise the sliding glass door as high as it will go and still slide easily.  This will keep someone on the outside from pushing up on the sliding door to get it off the rollers. Pushing up on the sliding door can also unlatch most factory latches.

To do this you will need the right kind of screwdriver, either a philips or slot driver.  By looking down at the holes on the bottom edge of the sliding door you can determine which screw driver will work.  There is a roller adjustment screw on both sides of the door. Insert the screwdriver into the adjustment screw in the door and you can raise or lower the door.  Raise one side a little and then the other in order to keep the edge of the sliding door aligned with the side jamb.  If it seems to hard to turn the screw you might need a friend to lift that edge of the door to take the weight off of the adjustment roller.
