A sash lock is a type of locking mechanism commonly used in windows and doors. It is designed to secure the sashes of a window or the leaves of a door in a closed position, providing increased security and preventing unauthorized access.

The sash lock consists of several key components, including a latch, a lock cylinder, and a strike plate. The latch is typically operated by a lever or a knob, which can be turned or pressed to engage or disengage the lock. When engaged, the latch extends into the strike plate, holding the window or door firmly in place.

The lock cylinder is the part of the sash lock that houses the locking mechanism. It can be operated using a key, a thumb turn, or a combination of both. The cylinder enables the user to lock or unlock the sash lock from the inside or outside of the window or door.

Sash locks come in various designs and finishes to match different architectural styles and preferences. They can be made of durable materials such as brass, steel, or aluminum, ensuring longevity and resistance to corrosion.

In addition to their primary function of securing windows and doors, sash locks often incorporate features like adjustable strike plates for proper alignment, anti-lift pins to prevent the removal of the sash or leaf, and even child safety mechanisms to restrict opening distances.

Overall, the sash lock is an essential component of any window or door, providing both security and peace of mind to homeowners and occupants. Its robust construction and versatile features make it a reliable choice for maintaining the integrity and safety of residential and commercial spaces.
