Door Hardware functions
These door hardware products will provide a locking function in the way of a "deadlatch" or "deadbolt" that keeps the door from being opened on the exterior side of the door. They can come keyed on the exterior side with a turnbutton or thumbturn on the interior side or keyed on both the interior and exterior sides.
- Single Cylinder Deadbolt
A single cylinder deadbolt is typically used on a front or back exterior door and is operated with a key from the exterior of the home and a thumbturn from the interior.
- Double Cylinder Deadbolt
A double cylinder deadbolt is typically used on a front or back exterior door and is operated with a key from both the exterior and interior of the home. Double cylinder deadbolts are recommended when a window is in close proximity to the door. The interior keyway prevents an intruder from accessing your home by breaking the glass and turning the thumb turn to open the door.
- A handleset is operated with a key from the exterior of the home and a thumbturn from the interior.
- Exterior Keyed Knob or Lever
- These can be used in places such as entry doors, garage doors or in combination with a deadbolt product.
A type of locking interior door product is most commonly called "privacy" or "bed and bath". This product provides a turn button on the inside and comes with an emergency release on the outside that allows the door to be unlocked by inserting an emergency release tool.
Non-locking products are typically called a passage or hall/closet. These products have a latch that retracts when they are turned and allow entry but do not provide a locking function.
A product that is considered non-functional is static or stationary. These products do not have a latch and do not turn or perform a function other than for decorative purposes. An example of this type of product is an entrance door handleset that is installed on the stationary double door.

Some styles of Weiser levers are handed, usually due to a curved design. There are left-handed levers and right-handed levers. To determine the appropriate handing for your door, look at the hinges from the exterior side of the door. If the hinges are on the left, you require a left-handed lever. If the hinges are on the right, you need a right-handed lever.

Latches that utilize interchangeable faceplates are referred to as universal or 6-way latches. Universal latches include a drive-in latch and both square and radius faceplates that can be attached to the latch to simulate a fixed faceplate latch. The 6-way latch designation comes from the 6 different door requirement combinations that the universal latch will accommodate (i.e. 3 door configurations x two backset options each = 6 ways to utilize).
