Cam Locks
Cam locks are used in a variety of applications but are most frequently found in filing cabinets, mailboxes, and lower security OEM applications. These high quality pressure cast locks can be keyed in many different ways to existing or new systems. They come in several different lengths and can use a variety of tailpieces or “cams” to interface with another locking mechanism.

Rim/Mortise Locks
Rim cylinder and Mortise cylinder locks are frequently found on commercial doors, entry glass doors, and some apartment doors. Read More about Mortise Cylinders V.S. Rim Cylinders

Euro Profile Cylinders
Euro profile cylinders (sometimes called DIN cylinders) are frequently used in locking devices in Europe and other parts of the world. These cylinders are available for different door thicknesses and featuring an adjustable cam actuator

Wall Mounted Locks
Wall mounted locks are locks that are actually mounted in the wall. The most common type of wall mounted lock would be the Knox-Box or fireman’s box style lock found in many larger businesses as an emergency access to the buildings keys. Wall mounted locks can be used for more than just key storage. Some act as small safes or item deposits.

Vending/T-Handle Locks
These locks are primarily found in vending machines and T-Handle locks, although they are sometimes used in other applications. T-Handle locks are frequently exceptionally easy to replace as when you open the device you are actually pulling the t-handle lock out. Placing a new T-handle lock back in when closing the device is all that is necessary to complete the upgrade. T-Handle locks generally come in two variants, a spring latch that allows the device to be re-locked without needing a key, and a dead latch that requires a key to re-lock the device.

Jimmy Proof Deadbolt
The jimmy-proof lock, properly installed, tends to be much more secure from forced entry than a deadbolt. Jimmy proof deadbolts are a surface mount product frequently found on apartments and double doors. They are sometimes preferred due to the minimal door modifications required. They are also unique as the deadbolt interlocks with the jamb bracket preventing it from being simply pulled apart or forced easily from the outside. A surface mount lock means the lock screws into the inside of the door rather than having a complex drill pattern like a standard deadbolt. Jimmy proof deadbolts only require a hole drilled straight through the door for the rim cylinder. If you have an existing Jimmy proof deadbolt you can generally replace just the rim cylinder to upgrade your security.

Rim Latch Locks
A rim latch lock has a standard or custom rim cylinder on one side and a surface mount latch lock on the other. Rim latch locks can auto lock the door behind you and are popular in some apartment complexes. Rim latch locks are generally not meant to take a large amount of force but can be paired with other locks when used on an external door.

Interchangeable Core (IC) Cylinders
Interchangeable Core Cylinders are frequently used in larger institutions and businesses and are known for their easy ability to re-key the lock by swapping out the core without taking the lock apart. The most popular I/C Lock brands are Best, Yale, and Schlage. Their figure-eight style cores are well known and are found in many places around the world. There are different I/C lock formats with the two most popular being Small Format Interchangeable Core (SFIC) and Large Format Interchangeable Core (LFIC). It is important to note that I/C cylinders can only be installed in housings specially meant for I/C cylinders. They cannot be installed in standard deadbolts or locks not meant to take an I/C cylinder.

Furniture Locks
This category of locks actually covers a variety of locks including cabinet, desk, and sliding door locks. There are two primary styles of furniture lock, bolt style and push button style. Frequently, furniture locks can be installed onto existing hardware that may not already have a lock installed.

Key In Knob (KIK) Cylinders
A Key in Knob cylinder is generally found at the heart of most knobs, levers, and lower cost deadbolts. They are also popular in a variety of OEM applications and even some sliding glass doors. A KIK cylinder is generally hidden inside of the lock with only the circular face of the lock being visible. Frequently, when you take the lock apart (knob/deadbolt/etc), you will find a KIK cylinder held in place with a screw. Unfortunately, while KIK cylinders all generally look similar, there are no standard specifications to their design. This can make replacing one cylinder with another of a different brand (or a high security model) challenging. Major manufacturers generally have one or more of their own designs for a KIK cylinder. Other manufacturers sometimes duplicate the style so that their cylinders can replace those produced by other manufacturers. Aside from the different sizes that KIK cylinders can have, they also have one of several different style tails on the rear of the lock. A floating tail is where the tailpiece can rotate a certain amount without the cylinder itself rotating. A fixed tail is where the tailpiece cannot rotate without the cylinder rotating.
