This is a video on rehanding an Atrium mortise lock. The latch on any lock or handle needs to have its slope-side facing the door
jamb so it can be depressed and the door can be closed. Our atrium lock is handed the wrong way because the
slope is facing away from the door jamb. So, to fix this, push the spring latch all
the way into the lockbox with your finger. You should be able to see a screw. Remove the screw, flip the latch, and, holding it in again with your fingers, secure the screw in place. The slope of the latch is now facing the
correct direction and the door can be closed. Thanks for watching our video. For more information, please visit our website at www.allaboutdoors.com.
