Door Hardware Functions and Applications
What you need:
- Front door
- Garage door
- Sliding glass doors
- The most common lock function for exterior doors is a keyed entry function. Locks with this function have a keyed cylinder facing the outside of the home and a thumbturn on the interior. When the door is locked, it can only be opened with a key from the outside. When the knob is turned from inside the home, and the thumbturn is unlocked, the door will open freely.
- Keyed entry locks are often used in conjunction with an auxilary deadbolt for added security. A single cylinder deadbolt has a thumbturn on the inside and requires a key from outside. Double cylinder deadbolts use a key on both sides of the door. This application is often recommended for doors with glass panels. If an intruder breaks the glass he will not be able to reach in and unlock the deadbolt without the key.
- Many homeowners choose handlesets for their entry doors rather than knobs or levers. Handlesets use a deadbolt to provide a high level of security, and are available in a wide variety of styles to complement the home's decor.
- A mortise or interconnected lock with a dwelling entry function is another option for exterior doors. This lockset features an integral deadbolt that is keyed from the outside and inside the home, both the deadbolt and the latchbolt are retracted by turning the knob. This allows for faster exit during an emergency.
What you need:
- Closet and passage
- Many homeowners will find that locks with a passage function are sufficient for most interior doors. This lockset has no cylinder and is freely operational from both sides of the door at all times. It is used on doors in hallways, closets, and other rooms where locks are not needed.
- Privacy locks are similar to passage locks, but they include locking using a push or turn button from inside of a room. They are used on bathrooms and bedrooms, where privacy is needed, and typically feature an emergency release mechanism on the outside.
- For home offices, consider using a free interior entrance lockset, which can be locked with a key from the outside. Occupants can freely exit the room at anytime without a key.
- If you have a storeroom or pantry that you need to keep kids out of, use a lock with a storeroom function. This lock is always locked unless opened with a key. When the door is closed, the lock automatically reverts back to a locked position. From inside the room, the door will open freely at all times to allow someone inside the room to exit.
Handing What you need:
- When you purchase levers, keep in mind handing. Doors can be left handed or right handed. To determine the handing of a door, face the outside of the door as though you are entering a room. If the hinge is on the left, the door is left handed. If the hinge is on the right, the door is right handed. Some handles are reversible, which mean they are positionable in either the left hand or the right hand configuration.
