A sash lock refers to a type of locking mechanism primarily used on windows and doors. It is designed to secure the sash or the movable part of a window or door in place, preventing unauthorized access or accidental opening. The term "sash" typically refers to a framework containing a movable pane of glass, often found in double-hung or sliding windows, but it can also extend to other types of doors or windows.
A sash lock usually consists of two main components: a latch and a lock. The latch is attached to the sash itself and engages with a strike plate or keep, typically mounted on the window frame or jamb. This creates a secure fastening when the sash is closed, preventing it from being opened from the outside. The lock component, usually a lever, knob, or key-operated mechanism, adds an additional layer of security by preventing the latch from being easily disengaged.
Sash locks come in various forms, materials, and styles to suit different types of windows and doors. They can be made from metal, such as brass, steel, or zinc alloy, or even from durable plastic. Some designs may also feature additional features like anti-lift pins or child safety locks, providing enhanced protection against forced entry or accidents.
Overall, the sash lock is an essential hardware element that combines functionality and security, ensuring the stability, integrity, and safety of windows and doors in both residential and commercial settings.
The word "sash lock" has a straightforward etymology.
The term "sash" refers to a type of window in which the frame is divided into two parts (known as sashes) that can slide vertically. This design is commonly seen in double-hung windows. The word "sash" derives from the French word "châssis", meaning frame or framework.
The word "lock" refers to a device used for fastening or securing something. It comes from the Old English word "locc", which means bolt or fastening.
When we combine these two words, "sash lock" simply refers to a locking mechanism specifically designed for sash windows to secure them in a desired position or prevent unauthorized access.
