Passage door knobs don't have an internal locking mechanism. Thus, it can't be used on exterior doors without an additional lock.
Doorknobs and locksets intended for interior use may have no water seal and may use a thinner protective coating. Doorknobs and locks intended for exterior use could easily be used indoors, but interior sets may quickly leak, corrode, or lose their finish if exposed outdoors.
Exterior door knobs have a much bigger job to do than interior ones. They're the main barrier in most homes between the house and anyone who hasn't been welcomed into it. An exterior door knob needs to be strong, reliable, and have a lock that works well. There are two main options within this category.
Passage door knobs are similar to dummy door knobs. They don't lock but are used to open doors and go between rooms. Passage door knobs are ideal for interior hallways, closets and other rooms that don't need privacy locks. They're also called unkeyed knobs.
Privacy knobs have a locking system but do not require keys. If you want to unlock the door, you can use a privacy emergency key instead. For passage knobs, you cannot lock them. The knob is purely for easy access to another room.
Passage knobs are interior non-locking door knobs that turn freely and don't include a key. They operate with a latch and require rotation of the handle to open the door. This type features two non-locking knobs on either side of the door and is ideal for hallways, closets, and rooms where privacy is not required.
Passage Latch Function
The latching mechanism can be retracted by both the inside and outside levers at all times. This door lock function is never locked and has no key or locking mechanism on either side of the door. It is often referred to as a passage latch instead of a lock.
Door knobs are not universal, but there aren't exponentially increasing options for what you need. You need to consider three things: the backset, the hole diameter (called a cross-bore) where the doorknob goes, and whether it's for interior or exterior use.
Hall & Closet Passage Door Knobs
Can be paired with a smart lock or keyless deadbolt on exterior doors or with non-turning knob for the interiors of smaller closets.
Door levers are left-handed, right-handed or universal. To determine what you need, look at the door from outside the house or room. If the hinges are on the left, look for a left-handed or universal lever. If the hinges are on the right, you need a right-handed or universal model.
Dummy door knobs have no connections to a latch, and you only pull the knob to open a door. These door knobs seem unnecessary. And so, you may be wondering if dummy door knobs are crucial to your home's security and where to use them. We have researched from the experts the suitable places for your dummy door knobs.
To have the door function properly, you will have to make sure that the door knob you buy is the correct size for your door. The standard size for a door knob diameter is either 2 3/8 inches or 2 3/4 inches and these knobs will usually fit doors that are anywhere between 1 3/8 inches to 1 3/4 inches thick.
While door knobs commonly come in standard measurements, they aren't universal. Standard-sized door knobs have a better fit with most modern doors because they follow this standard. On older doors, they most likely won't fit because the doors have smaller measurements.
Measure from the edge of the door to the centre of the door knob or handle. The industry standards are usually either 44mm / 57mm / 82mm / 107mm / 130mm. Ideally you will try and choose the backset measurement that sites the door handle in the middle of the door stile.
Available in finishes like chrome and brushed nickel, levers handles throughout your home are a great modern upgrade. This is a good look for homes built in a modern, contemporary, midcentury or transitional style.
Matte Finishes
Another highly popular finish in 2022 is the matte finish. The matte finish looks pretty rustic, which allows the matte doorknobs to match your natural finishes. The most popular matte finishes are found on black, gray, charcoal, and other dark-colored doorknobs.
Matte black in particular, will be incredibly popular for 2021 and going into 2022. In fact, matte black is trending in all forms of hardware - from cabinets to door knobs and light fixtures.
The main types of door functions are Passage (doors that don't require locking), Privacy (a door that can be locked by a button on the inside), Dummy (has no mechanical latch and acts only as a pull), and Interior Mortise (door with an active latch with skeleton key lock).
A latch fastens a door, gate or window in position but does not provide security. (See Wikipedia.) A lock prevents anyone without a key from opening a door/gate/etc.
PASSAGE SETS are used where doors do not need to lock. There is no key cylinder and no means to lock a passage set. PRIVACY SETS are often used for single-occupant restrooms or dressing rooms.
Dummy knobs have no working parts. Dummy knobs do not turn. They don't have locks, axles or latches. Dummy knobs are fake, fixed knobs used to open and close a door that doesn't have a traditional latch.
A double cylinder door knob is a door knob that is keyed on both sides of the door, or in a place where the door that needs the option of locking on either side of the door.
Hall and closet door hardware refers to non-locking knobs and levers, sometimes called Passage hardware. They are ideal for rooms and doors where locking is not needed, such as a closet.
