Introduction
A fastener is an integral part of the window hardware. A fastener is
actually a mechanical device that allows one to fasten a window. They

A window closing in a clockwise direction would need a right handed
casement fastener. On the other hand, a window closing in an
anti-clockwise direction requires a left handed casement fastener.
