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 please be aware that entry sets have differing requirements for hole location depending on the type of lock and design chosen. For this reason it is best to choose your lock and give it to the door prep person to assure holes are bored in the proper location. Some common door preps are shown 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.
MOST TUBULAR HANDLESETS require a 5-1/2" center to center door prep. Please see the template included with your particular hardware for the exact specifications.
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.
