The following group of door pair elevations is a sampling of the variations possible with escutcheons. The grouping shows that the alignment of the divided lites, in combination with the escutcheon method, control the lever height options. This group shows primarily "three lites" high divided conditions. Four lite high divisions would create another series of conditions. Maintaining consistent handle heights with variety in door heights and divided lite heights is the design challenge.
There are a lot of subtleties that come into consideration when choosing a layout. Our cad department is available to sketch out different scenarios to help define the best solution. Or, here is a quick list of variables that would be considered to layout a design:
1. Desired handle height
2. Desired layout of the breakups in the glass (if divided lites)
3. Size of the body of the lock box. (to allow proper clearance from glass and divided lite bars)
4. Key above or key below the handle (typically it is key below except for commercial egress lock box)
5. Escutcheon length and location of the escutcheon.
6. Maintain needed clearance for the lock box itself. (see lockbox size guidelines in illustration)
