Main Trim Components
Knob (reasonably symmetrical), lever, thumb grip.
Some lock types/door conditions dictate what can be used. Thumb grips are typically only used on large exterior doors, and currently with decreasing frequency. For owners with functionality concerns, we suggest a lever be used.
Spindles
Connects interior to exterior trim while activating lock as they are operated.
Varying sizes, orientation, length, function (split or solid), and means of gripping the trim.
Sub-Rosette
Means of securing trim to the face of the door.
Available threaded for rosettes or without threading for escutcheons. Active have a circular center, full dummy have a spindle shaped center, and single dummy utilize a half spindle in its construction.
Emergency Release
Used to easily gain access to a room in cases of emergency (bathroom, bedroom).
Available for use with a key or as a coin turn. Also available for use with a key or as a coin turn. Also available colored to indicate if the room is secured shut or vacant.
Escutcheon
An extended high trim piece positioned between the main trim component and the door. Typically allows for fitting more than one trim piece to it (knob and turn piece, etc.).
Some exterior doors require escutcheon plates. Commonly used with ornate designs and areas with taller doors.
Rosette
Sits behind a knob or lever and serves as part of the rim. Typically smaller than an escutcheon and reasonably symmetrical.
Available for active/dummy (or push button privacy in some cases). Concealed or exposed fastener by design. A rosette paired with a turn piece on a separate back plate is referred to as sectional.
Turn Piece
Utilized to extend a bolt, typically from the inside of the door. Privacy, entrance, patio, etc..
Typically the same style is utilized on interior and exterior doors. Most often suited to other trim selection.
Closet Spindle
Same intent as spindle, but with a minimal trim piece integrated on the interior.
Intended for use on the interior of a closet where a positive latch is preferred. Less common. Meant for use on a closet door to be able to exit from the inside. Not easy to turn.
Cylinder Collar
Serves the same purpose as a rosette, but sits behind the cylinder.
Is not needed on an escutcheon. Typically used for section trim sets.
