Interior doors refer to doors inside of your home. A door handle can function in three different ways - as a simple pull, as a latch that keeps the door closed, or as a privacy lock. Many handle sets are available in all three options; the handles look the same, but operate differently.
Dummy Sets - A dummy set is the best choice for doors that don't require a latch - such as hallway doors, cabinets, or bi-fold pantry doors. Dummy sets or dummy singles (also known as half-dummy handles) function as pulls and do not turn. Dummy sets are surface-mounted to the door and usually take only a few minutes to install with screws.
Passage Sets - A passage set is used for interior doors that don't need locks but do require a latching feature. These types of handles and knobs are often installed on doors in the general living area, dens and basements.
Privacy Sets - Privacy sets are used where locking functionality is desired, such as bathrooms and bedrooms. They have a pin that enables locking from the inside, and an emergency release access hole on the outside.
