Use 1” hole saw to drill door edge  

2"deep. Hole must be drilled  

parallel to the door face  

and level. 

 

It is very important that the bolt assembly is flush  

in the mortise. If the door is beveled, ensure that  

the bolt assembly is flush with the low  

side of the bevel. The barrel of the bolt  

must be parallel to the door face and  

perpendicular to door edge. Trace with  

pencil or utility knife to outline mortise.
Mortise edge of door to accept bolt assembly  

and face plate. 
Insert latch and tighten screws.

Important Notes 

If you are prepping the door for a standard 

round deadbolt, leave at least 8" between the 

center of deadbolt and center of UltraLatch® 

bolt to allow clearance for UltraLatch® handles. 

If using any other type of deadbolt, measure 

before placing hole to ensure that you have 

enough clearance.
