Yes that is a sliding door!
This mag lock was installed by a carpenter, it is switched via a cheap hotel style locking system. Obviously this did not work long due to the lock grabbing the armature plate as soon as it slid close to the face. The door would not close and quickly the plate was dislodged. The mag was also packed down with cheap plastic spacers.
An experienced locksmith was called in and paid to install the proper L&Z configuration. The L&Z bracket was supplied with the lock but the original installer obviously did not have a clue.
Thanks to the locksmith (Luke) for the photos. Another reason only qualified and experienced tradesmen should be used.
