Introduction
Latch is typically a fastener, designed to join two or more objects or
surfaces together. At the same time, a latch allows for the regular
separation of objects or surfaces. The design and style of latches are
diverse and depends directly on the size and type of window for which
they are used.
Window Latches can be a single piece flat spring of metal or multi
point cam latches. There are some spring-loaded window latch that can be
used to lock the window in open position. Turning the lever allows the
bolt to close under spring pressure. Spring loaded latches are designed
for easy release and provide security to the window. Latches are
generally installed vertically at the top or bottom of the window.
Materials Used
Window latches are usually cast of metal or metal alloys. Some of the
common materials used are:
- Brass
- Iron
- Aluminium
- Bronze
Window latches are available in various finishes. Polished brass
finish, black finish, zinc finishes are popular for window latches.
Latching Mechanism
There is a storm window latch mechanism that allows easy removal of a
storm window sash when the latch is set in one position. At the same
time, the window sash is protected within the mounting framework when
the latch is in a different position. The mechanism also permits the
sliding up and down movement of the window. The latch mechanism is
facilitated by a spring slider along with a low friction slide
component.
