4. PRE-INSTALLATION ASSESSMENT
4.1. Mechanical
The first decision regarding installation is whether the YD25K will be mortised or surface mounted to the door / door
frame. Mortise installation ensures a discrete solution as the lock and strike plate can be embedded into the door
and frame, however in some instances this is not possible. Glass doors for example require surface mounting the
lock which is done with the aid of the YD25K housing. Attention must be made to where the key cylinder will be
situated and if it is easy to access with a key for the manual override operation.
