When it comes to security, there are a variety of locking devices available to protect your property. Combination locks, knob locks, cam locks, padlocks, mortise locks, smart locks, and keypad locks are some of the most common types of locks used for security. Combination locks have one or more numerical dials that open the lock when the correct combination is entered. Knob locks are the most common type of door lock available and the primary security method for most doors.
The lock cylinder is located on the knob itself instead of on the door, so knob locks should not be used on external doors, as they can be easily broken with basic tools such as a hammer or key. Cam locks consist of a fastener with an attached arm, or cam, that rotates to lock it. They are cylindrical and have a metal tube with a hole on one side that helps position the bolt when inserted. These door locks are commonly used on vending machines, filing cabinets, desks or cabinets to prevent unauthorized access.
In fully constructed cabinets, they are invisible for the most part. Certain cam locks fully secure cabinet doors, making them attractive for protecting sensitive materials. Padlocks are easy to recognize both because of their mobile nature and because of their shackle shape with a loop-shaped handle. They can be designed with shoulders raised around the shackle, also known as protected or wrapped padlocks, to prevent bolt cutters from going through them. Keypad locks can be opened with an attached numeric keypad instead of a key.
They can be battery operated or mechanical and typically use bolt locks, knob locks, or mortise locks for the actual locking mechanism. These locks offer greater versatility and allow keyless entry, although many also have holes to open other unlocking mechanisms. Some keyboard locks allow for multiple custom codes, so building managers can easily restrict access. The above list does not include everyone; there are many other door locks that fall into the seven categories of knob locks, bolt locks, cam locks, padlocks, mortise locks, smart locks, and keypad locks. For example, door locks with a lever handle are used for interior doors and work much like knob locks.
The orientation of the door is another crucial factor for the installation of the lock; some work with a specific hand while others work for both. Deadbolt locks can be installed on any type of manual door without any problem; the orientation of the door depends on which side of the door has the hinges. Cam locks are a very versatile type of lock that is most commonly used for low-security applications; you'll usually see them in filing cabinets and mailboxes. Cam locks are available in a wide variety of different lengths and in a handful of different subtypes; they are one of the most customizable types of locks that exist. Padlocks are not embedded in a door or furniture; they can be attached or removed at will by using a shackle to hold a door closed or an object in place. They are often used to lock sheds, school lockers, and even luggage; while padlocks are common, they're also considered a relatively weak lock because it's easy to break them if you have access to a cutter, drill, or hammer. Keypad locks are unlocked by entering a certain series of numbers into the lock; this means that only someone who knows the correct number sequence can unlock them.
The number sequence can also be reset to keep the code secure. Key locks use a small key instead of a numerical sequence; while some people prefer not to have to remember a set of numbers to access their belongings, there is a risk of losing the key because they are usually quite small. Bolt locks can be installed on the surface of the door or inside it for added security; also known as “vertical bolt”, this lock is commonly used on double doors and entrance doors to apartments. Jimmy Proof locks use two interlocking vertical bolts; when activated they enter a locking plate which makes them difficult for potential thieves to open. Handle locks can be found on all types of doors but their strengths and weaknesses can make one better than the other depending on where you use them.
