Types of Cylinder Locks
There are different types of cylinder locks that you can choose from. Although their main function is to provide security, each has unique features that can suit the needs of the homeowners.
Rim cylinder locks
A rim cylinder lock is typically mounted at the surface of the door by simply securing it with screws. Once the lock is installed, the body of the lock remains visible. In terms of the bolt, it commonly includes a spring-loaded sliding latch bolt or a deadlocking bolt.
Since most rim cylinder locks are warded, they are only used as obstructions but not as entry door locks. The screws are visible and can be easily removed. Aside from that, rim locks cannot stand the force of strong kicks.
Most homeowners use rim cylinder locks to increase their privacy inside their homes. These locks are usually installed in bedrooms and bathrooms. Because of their classic and elegant design, they are also used for aesthetic purposes.
Double cylinder locks
Allowing locking and unlocking on both sides of the door, a double cylinder lock is preferred by many because of the security it offers. It would take a key to lock and unlock the door since there is no thumb turn.
This lock is often placed near glass panels. This would prevent burglars from breaking in even if they break the glass. Without the key, it is impossible to unlock a double cylinder lock.
However, the National Fire Protection Association (NFPA) Life Safety Code 101 prohibits the use of double cylinder locks for egress doors. With these locks installed, the owner of the house would find it difficult to immediately get out of the house in case of a fire emergency.
Euro cylinder locks
Euro cylinder lock, also called a barrel lock and pin tumbler, is widely used in residential and commercial properties. It is easy to combine with different locks because of its “keyed alike” feature.
There are different types of euro cylinder locks such as a full or double euro cylinder, full thumb-turn euro cylinder, half or single euro cylinder, and half thumbturn euro cylinder. Users prefer this lock because they can be used on many door materials.
Mortise cylinder locks
Although a mortise cylinder lock looks like a rim cylinder lock, they are totally different in various aspects. Mortise cylinders have threaded exteriors and cams while rim cylinder locks have stems and bolts.
In terms of lock bodies, mortise cylinder locks are fitted inside the door so they cannot be easily seen. Rim cylinder locks, on the other hand, have visible lock bodies since they are located outside the door.
Door cylinder vs Core
Aside from knowing the different types of cylinder locks, it is also necessary that you can differentiate a door cylinder from a core so that you won’t be confused when you choose a cylinder lock for your door.
The core is just one part of the cylinder that holds the pins of the lock. Meanwhile, the term “door cylinder” or “lock cylinder” refers to the lock core plus the housing that contains it.
