The most common lever lock is known as a cylindrical lock. This lever lock is
installed on the door using a 2 1/8 inch hole drilled through the door with a 1
inch hole from the edge of the door. It also uses two additional holes outside
the perimeter of the 2 1/8 inch hole to stabilize the lock and prevented it from
twisting on the door and causing a malfunction. The mounting post hole locations
vary across the manufacturers.
When choosing a lever lock one needs to always take into consideration how often
the door is going to be used. If the door is in a high traffic area than a grade
1 lock should be chosen for this application. On a door that is used about 500

A grade 2 lock can be used on a door that has a traffic level up to 300 to 400
times a day. The grade 2 lock should last approximately 5 to 7 years with
minimal maintenance for needing replacement.

traffic areas. Mortise locks are used on most commercial office buildings.
Mortise locks provide more choices for different types of trim.
