These timber window stays are specially designed by Australian manufacturer, Tradco Hardware, to suit your single or double casement windows with wooden frames. Sill mounted, they are held open or shut with the included keeper. The aged chrome wood screws are also included for easy installation. Choose to increase the level of security with an optional hand-aged chrome-plated locking pin, which will further secure your timber window open or closed. There are smaller aged-chrome window stays available.
