Interior Door Hardware Functions

Passage, Privacy, Double Dummy, Single Dummy Interior Functions

Interior Functions

There are four different functions for interior doors. What type of room your door leads to, such as a bathroom, bedroom, closet, etc., will help determine which function will work best. All of our interior hardware sets with latches work with doors with a standard door thickness range of 1-3/8″ to 1-3/4″.

Passage Set

The knobs turn and operate a latch but do not lock. Passage sets are typically used on interior doors or doors with a separate deadbolt. They are ideal for closets, hallways, or rooms where no locking mechanism is needed.


BOX INCLUDES:

  • 2 Knobs or Levers
  • 2 Plates or Rosettes
  • 1 Passage Latch (2-3/8″ or 2-3/4″)
  • Matching strike plates and screws

Privacy Lock

The latch on a privacy set will have a locking mechanism. A privacy pin next to the knob or lever provides locking through the plate or rosette. Privacy sets are ideal for bathrooms, bedrooms, or rooms where a locking mechanism is needed.


BOX INCLUDES:

  • 2 Knobs or Levers
  • 2 Plates or Rosettes
  • 1 Privacy Latch w/ Privacy Pin (2-3/8″ or 2-3/4″)
  • Matching strike plates and screws

Double Dummy

A double dummy set includes hardware for each side of the door, yet with no lock or latch. The knobs or levers don’t turn or operate a latch. Double dummy sets are ideal for closet doors, pantry doors, or side-by-side French doors (used with roller catch, flush bolts, or surface bolts). Double dummy sets are surface mounted or thru-bolted and can be installed on pre-drilled doors with modification.

A single dummy set includes hardware for one side of the door. The knobs or levers on this door set don’t turn or operate a latch. These sets are ideal for closet doors, pantry doors, or side-by-side French doors (used with roller catch, flush bolts, or surface bolts). Single dummy sets are surface mounted or thru-bolted and can be installed on pre-drilled doors with modification.
