FAQ:

Q: What is the best lock for a sliding glass door?

A: Dropping a stick in the track will only lock one sliding door. The best way to lock these doors is to lock one door against the other. The “Dixie” lock did this more simply and effective than anything on the market, and it still does. Sliding patio doors in south Florida were made better than doors in New Jersey.

Q: How do you fix a sliding glass door lock?

A: Place the interior side of the door lock frame into the door. Place the door handle over the screw holes on the interior side of the door frame, followed by the screws, and hand tighten the screws. Tighten the screws with a Phillips head screw driver.

Q: How do you fix a sliding door latch?

A: Take your graphite pen and insert it into the lowermost screw hole quickly to prevent the latch from falling into the frame. Then, unscrew the mounting screws for the lock and use a pair of needle-nose pliers and pull the body out of the door completely.

Q: How do you fix sliding glass doors?

A: To remove a sliding glass door, pull the rollers into the door by turning the adjustment screws counter-clockwise, tilt the top of the sliding door, and lift it from the door track. Undo the screws that hold the fixed glass in place, tilt its top, and remove the door.
