Zatrzask

Zatrzask is the Polish term for a latch, a mechanical fastener used to hold two surfaces, such as a door and its frame, in a closed position. Latches are designed to secure objects while allowing convenient opening when needed. They are commonly found on doors, gates, cabinets, and drawers, and come in a range of sizes and configurations.

Types of latches vary by mechanism and application. Spring latches use a spring-loaded bolt that retracts when a handle or knob is turned, then returns to the extended position to engage a strike plate. Tubular and mortise latches are widely used on interior doors, with the former mounted in a cylindrical bore and the latter installed in a recessed pocket. Rim latches sit on the surface and are often used for furniture or lightweight doors. Magnetic latches use magnets to hold components in place and are common in certain cabinet systems. Electric or electronic strikes enable access control by releasing the latch when an authorized signal is applied.

Key components include the latch bolt, a strike plate, a faceplate, and the operating hardware (knob, lever, or handle). Materials range from steel and brass to zinc alloys and plastics, chosen for durability and corrosion resistance. Maintenance is typically minimal but may involve periodic lubrication and inspection of springs and mounting screws.

Zatrzask devices are valued for simple operation and reliability, though they offer varying levels of security depending on design and accompanying hardware. For high-security needs, they are often combined with additional locks or electronic access systems.
