Emtek Door Preparation
Emtek locks fit into a standard American style tubular door prep. If you are replacing
existing locks then your door preps will most likely be correct for Emtek locks.
Just determine the backset and you're ready to order. If you're installing locks
in new doors that do not have a door prep you can follow the instructions below.
BACKSET - In the U.S. there are two common backsets
for residential locks, 2-3/8" and 2-3/4". The backset is the distance
from the edge of the door to the center of the 2-1/8" bore hole. We will pack
your locks with a 2-3/8" or 2-3/4" latch depending on which backset you
specify. Dummy sets have no latch and are surface mounted so you can install a dummy
set wherever you choose on the door.
PASSAGE, PRIVACY, KEY-IN-KNOB OR LEVER, AND DEADBOLT LOCKS fit
into the door prep shown to the left. Bore a 2-1/8" hole through the door.
The center of this hole should be located 2-3/8" or 2-3/4" back from the
edge of the door (this is the backset dimension).
Bore a 1" hole in the edge of the door located on the centerline of the 2-1/8"
hole. The latch will fit into the 1" hole. Chisel out a 1" by 2-1/4"
rectangle on the edge of the door, 1/8" deep. The faceplate of your latch will
sit in this recession.

Recess for Latch Faceplate
KEYED LOCKS WITH SIDEPLATES require two sets of holes with a center-to-center
distance of 3-5/8" between the two sets of holes.
DUMMY SETS require no door prep. Dummy handles are surface mounted
and may be located anywhere on the door you choose, but they are usually located
to match the appearance of nearby operating locks.
