Lockset
A lockset (alternatively lock set) is the hardware and components that make up the locking or latching mechanism that can usually be found on a door or other hinged object but can also include sliding doors and dividers. The components of a lockset can include (but are not limited to) the door handles (commonly both inside and outside), latch bolt, dead bolt, face plate, strike plate, escutcheon, thumbturn, push button, turn button, and other trim. The lockset and associated hardware typically defines a door's function and how a user could (or could not) access the two adjacent spaces defined by the opening associated with the lockset.
The Americans with Disabilities Act of 1990, under Title III, and many state and local governments regulate locksets in buildings occupied by the public. Typically, locksets that employ doorknob-controlled latches are forbidden for public use in favor of lever handles, which are easier to operate by gravity instead of the grasping and turning required by knobs. Many municipalities also regulate locksets in terms of fire rating, using standards determined more broadly by national or international organizations such as Underwriters Laboratories in the United States or the International Code Council, which are often supplemented by local governmental organizations (e.g. New York City's Materials and Equipment Acceptance (MEA) Division of their Board of Standards and Appeals (BSA)), or by local building codes. For example, mandates of building code may forbid (e.g., E2141/F16 "Double-Keyed Deadbolt") from group occupancies, or require (e.g., F93/F15) certain functions on hotel or motel doors.
The American National Standards Institute (ANSI), a private non-profit organization, and the Builders Hardware Manufacturers Association (BHMA) administer and coordinate voluntary standardization to develop and maintain performance standards for builder's hardware. Locks and handle sets are covered by standard A156.2, deadbolts by A156.5, and finishes by A156.18.
The grade specified according to the standards of ANSI/BHMA indicate the security and durability of the lockset.[citation needed]
Commercial, highest grade security and durability; can survive a 360-pound (160 kg) weight test.
Residential, with excellent security and durability; can survive a 250-pound (110 kg) weight test.
Residential, minimum acceptable grade.
The lockset's latching (locking) mechanism may be of the mortise or cylindrical type. The mortise mechanism is enclosed in a box (usually metal), requiring installation in a rectangular cavity carved into the edge of the door. The cylindrical mechanism is typically installed into the door via a cavity that can be simply bored through the door, usually by using a hole saw.
