Belmont Single Hung Window Ring - Antique BrassOur Belmont window ring is designed for use with wooden window sashes. Its a simple design that offers an easy way to raise and lower the top section of the window. Antique brass is whats called a 'living' finish because it reacts to the air and moisture around it, causing it to darken (especially in the areas you touch most). Weve given it a head start by ageing it by hand, so it has that antique look right out the box. Made from solid brass For use
