Lock mounting methods for narrow stile aluminum doors 4104 Mounting Bridge

Method A: 4104 Mounting Bridge: Method A spans the stile with a steel bridge at the top and bottom of the lock. A simple handle (Adams Rite Installation Tool 4075) is used to position the bridge accurately in the stile while its two screws are tightened to form a web in the door. Resilient washers allow for minor adjustment to fit the lock flush in the door.
