There are four pairs of complete swing arm style window curtain hangers in this kit. Each die cast arm includes it's adjustable depth mounting bracket. All have an Art Deco look to them. The arms have a telescoping rod inside. Maximum curtain width would be about 18". Minimum would be about 12". They'll need a little clean up (there's some paint residue here and there), but overall for being 80 to 100 years old, they're in pretty nice condition. There are even eight curtain hooks included.
