In this instructional video, you’re shown how to adjust the handle and lock on your Milgard sliding glass door. You should have a basic understanding of simple hand tools to undertake this project. Remember to wear eye protection and keep pets and small children out of the area when performing this process.
The tools required for this project include:
- Putty knife
- Phillips screwdriver
- Safety glasses
Pull the sliding glass door open with the handle. The lock snib is the locking device that releases and unlocks the door. Once you know how that works you’ll want to check the strike plate. The strike plate is located across from the lock and inside the door frame. You can move it up and down if the sliding glass door does not work properly, and miss aligns with the strike plate. In the center of the strike plate, you’ll see the Milgard logo on the strike plate cap. On the snib, the engagement tongue must run into the Milgard logo. If above or below the logo, the lock will not engage.
To adjust the strike plate, use a putty knife, remove the strike plate cap to expose the adjustment screw. Then using a phillips screwdriver back out the screw. Back out the other two screws at the top and bottom of the strike plate. The strike plate can be moved up and down accordingly. Once in proper alignment, re-insert the screws, then double check your door lock once this is place.
