Commercial Lock Sets

Lockset Types

Lock Sets not only keep your establishment secure but also serve a valuable purpose.


Cylindrical Locksets are by far the most popular. There are two types, lever locks or knob locks.


Mortise Locksets provides the highest security since the lock body is actually located inside of the door.

Lockset Functions

There are many different lock functions for whatever application you require but there are four types that are used most often:

ENTRY FCommercial Lock SetsUNCTION: This lock has a key on one side and a push button on the other. When the button is depressed, it can only be unlocked from the outside with a key. Turning the handle on the inside will make the button pop out which unlocks the door until either the button is depressed again or it is locked from the outside with a key. This is mostly used on doors that require some type of security such as exterior and office doors.

STOREROOM FUNCTION: This lock has a key on one side and a blank handle on the other side (no key or button). It remains storeroomlocked all the time from the outside (key side) and requires the key to open it every time you open the door. It is always unlocked from the inside. This is mostly used on storage and utility rooms or a janitor’s closet.

privacyPRIVACY LOCK: This lock has a push button on one side and an emergency release on the other side. It is made so that it can be locked from the inside but can be opened from the outside with a tool (usually a coin or screwdriver will do) in case of an emergency. This is mostly used on bathrooms.

passagePASSAGE FUNCTION: This has no key or push button on either side. It consists of two blank handles. Both sides are always unlocked. This is sometimes used on stairwell doors or any other doors where all you require is to have the door latch behind you but not lock so that it can be opened at all times.

Fail-Safe VERSUS  Fail-Secure Hardware

The difference is whether or not the lock requires power to activate it or to release it. Fail-safe is when the door unlocks when the power fails. Therefore power is required to keep the door locked. The opposite is true of fail-secure. Fail-secure is when the door is secure and cannot be opened when power is removed or disconnected. This means that power must be applied in order to operate the lock.

Magnetic locks

Magnetic locks work with DC current, usually 12 to 24 volts. All magnetic locks are fail-safe and need a constant power source if they are to remain locked.  It is usually best to use a backup power source with magnetic locks. All magnetic locks are silent even when powered and locked. Make sure the magnetic locks are installed correctly so that they do not cause a fire hazard.

Electric strikes

Electric strikes can be 12 or 24 or even a higher voltage and they may take AC or DC current or both. Electric strikes may be fail-safe or fail secure. As stated above, a fail-safe electric strike needs power in order to stay locked. A fail secure electric strike stays on with or without power.
