Different Lock Styles:
Lever Lock: The cylindrical lever lock is the most common commercial lock. They can be purchased in different colors and functions based on the users individual needs.
Mortise Lock: Mortise Locks are often seen in high rise commercial properties. Their popularity in recent years is based on the fact that they can be dual action (latch & deadbolt) while still allowing single motion egress to meet most fire codes.
Deadbolt Lock: Deadbolt locks can be single or double side keyed. When activated a bolt is thrown from the lock into the frame making a secure connection. Deadbolt locks are often considered more secure than lever or knob style locks.
Exit Device Lock: Exit Device locks are also known as Panic Bars. Exit devices are mounted on the egress side of the door, allowing people to exit by simply pressing in the bar. There are many different style exit devices but they all operate in the same manner. Based on the occupancy level of the given space they are sometimes required by the fire marshall.
Lockset Functions:
It's important to also understand that in addition to the different style of locks listed above that locks also come in different lock functions. Based on the installation of the particular lock you will also need to decide the purpose of the lock. Below is an explanation of the different functions:
Passage Function Lockset - passage sets are not locks in the true sense of the word, they incorporate a lever or knob on either side of the door and a latch to hold the door shut. There is no place for a key, as no lock cylinder is included.
Privacy Function Lockset - privacy locks are the type of locks generally used in restrooms, residential bedrooms, or sometimes offices. They contain no cylinder so they are not key operated. They can only be locked from the inside for privacy, usually by a pushbutton built into the knob or lever. They generally include a place for emergency access from the outside, often using a small screwdriver or pin to unlock the outside knob or lever through a hole in the trim.
Entrance Function Lockset - entry locks may be locked by pushing or turning a button on the inside and are unlocked by a key from the outside. This is the most common type of commercial and residential lock function, often found on office doors and exterior home locks.
Classroom Function Lockset - classroom locks (maintained) are always locked and unlocked from the outside by key. This style lockset can be left locked or unlocked from the outside via key. The inside knob or lever is always free for immediate exit.
Storeroom Function Lockset - storeroom locks (momentary) have a fixed outside knob or lever, and the latch is retracted by the key from the outside. This style lockset can not be left unlocked, it is always locked from the outside. The inside knob or lever is always free for immediate exit. This function lever is often used in access control systems incorporating electric strikes, this ensures the access system is not circumvented by leaving the door unlocked.
Asylum Function Lockset - asylum locks have cylinders on both sides and are always locked on both sides. A key is required for entry and exit. This is not a common lockset and you must be careful you are not using this lockset in violation of fire code. For commercial applications you will really only see this function lockset when sub-dividing a space, again consult your local fire marshall before using this function lockset.
Door Hand - How to Determine
Door handing is determined when standing on the outside or keyside of the door. Door handing is necessary to know when installing door hardware such as door pivots, door closers, latch guards, and handicap door operators . Handing of the door is also important to understand if you are installing locksets that are handed such as mortise locks and mechanical cipher locks.
