Types of Locks You Need to Know
Locks are mechanical or electro-mechanical devices used to secure doors, windows, etc. to prevent access to homes, rooms, closets, etc.
Lock types are many and include bolt, pad, cylinder, tubular, as well as electromechanical varieties. Other kinds of locks include padlocks, cabinet lock, power grid substation lock, etc.
Padlocks are often used to lock doors, cabinets, and boxes. It’s almost universally applicable to anything with a buckle and eye protector. Locks are generally made in metal for security purposes and can often be found in a variety of aesthetic finishes. Padlocks are often brass for corrosion resistance but can be made from steel as well, with solid or laminated bodies.
Cabinet locks are often used in industry. It can be widely used in power cabinet, industrial cabinet, outdoor cabinet, communication, network cabinet and distribution cabinet. All metal, reasonable design of standard structure, installed on the cabinet body that can be embedded, safe and reliable, not easy to lose and damage.
The popular cam lock is similar to a cam latch without a handle and is used to secure cabinet doors, etc. usually by a quarter turn tab that rotates and draws tight the door against the door frame. A cam lock differs from a cam latch in that it doesn’t provide an opening means; the cabinet door must be opened with a separate pull, lip, etc. Cam latches can be lockable.
Mortised locks for buildings and residences are rated on their secureness on three levels as defined by ANSI standards (see References, below). Other locks are selected for particular applications, such as display cabinet locks. Convenience, multi-party access, tamper-resistance, etc. are other considerations that can influence a lock purchase.
Security is relative, so a lock on a filing cabinet may do little more than keep honest folks honest, while hardened, hidden shackle padlocks are designed to thwart direct attacks. Deadbolt locks are generally considered more secure than spring bolt locks because their bolts are actively held in place by the lock cylinders and not just by springs.
