GLOSSARY
This is the portion of the set operated by the handles, cylinders, thumb latches and turn pieces.
Multi-Point Lock Mechanisms
Mechanisms that latch the door at several points along the length of the door instead of a single point in close proximity to the handle. Multi-point locks are provided with French doors made by most of the major window manufacturers. Due to the variety of multi-point sets available, Rocky Mountain Hardware recommends that a copy of the existing lock trim or a factory drawing be sent to us so our trim can be machined correctly to match the lock in the door.
American or U.S. Cylinders
Refers to the type of cylinder used with several types of multi-point lock sets. These cylinders are attached to the escutcheon and do not vary in length, but the tailpiece length varies according to door thickness.
European Profile Cylinders
The other type of cylinder used with multi-point lock sets. These cylinders slip through the exterior escutcheon, the door and the interior escutcheon and are held in place by a set screw through the edge of the lock and vary in length for different door thicknesses.
Dead Bolt
A locking mechanism that is separate from the latching mechanism in a door set. A dead bolt can be locked by a key or a turn piece. Rocky Mountain Hardware can provide separate dead bolt trim that is used above a handle set or can incorporate the dead bolt and handle trim onto the same escutcheon.
Mortise Bolt
A locking mechanism that is separate from the latching mechanism and is operated by a turn piece. It is commonly used for interior applications to provide privacy on bedroom and bathroom doors.
Mortise Lock
This mechanism integrates the locking and latching mechanisms into a single cartridge style lock. The mortise lock is available in a variety of functions such as entry, patio, privacy and passage.
Spring Latch
A latching mechanism operated by the handles.
Cylinders
A portion of a lock where the key is inserted to lock or unlock the set. There are several different kinds common to Rocky Mountain Hardware sets.
Mortise Cylinders
Mechanisms that are threaded into mortise locks, secured by a set screw through the edge of the lock and vary in length for different door thicknesses.
Rim Cylinders
Mechanisms used in dead bolts that are mounted with screws from the opposite side of the door. They do not vary in length, but the mounting screw and tailpiece lengths vary according to door thickness.
