They come in a variety of designs and materials, and can be either surface-mounted or recessed into the window frame. The basic function of a casement fastener is to hold the window tightly against the frame, which helps to prevent drafts and air leakage. They work by using a cam-style mechanism to pull the window in tight against the frame. Some common types of casement fasteners include: Hook fasteners - these have a hook-shaped arm that locks onto a keeper mounted on the window frame.
Wedge fasteners - these use a wedge-shaped arm to pull the window in tight against the frame.
Espagnolette fasteners - these use a series of gears to pull the window in tight against the frame.
Folding fasteners - these fold down to secure the window, and can be either surface-mounted or recessed into the window frame.
When selecting a casement fastener, it's important to consider the size and weight of the window, as well as the overall style of the interior. A well-chosen casement fastener can add a touch of elegance to the window while also enhancing its functionality.
