Sash Locks

The majority of these antique window locks are used for old (or new!) wooden double hung windows. They are installed on what is known as the “check rail”, which is the bottom rail of the upper sash and the upper rail of the lower sash. The top rail of the lower sash and the bottom rail of the upper sash meet when a double-hung window is closed. There are also locks in this category for casement or inward opening windows.

You might also want to check in Cabinet/Furniture>Latches since cabinet latches and window locks were oft times used for the same purpose.
