The Deco collection from Nostalgic Warehouse features the straight lines and modern look of the Art Deco trend in the 1920's and 1930's. Deco works well for a home that needs an understated look. The style has been modified slightly to fit on modern pre-drilled doors. This passage set has an active latch with no locking mechanism. This set will work on doors between 1 3/8" to 1 3/4" thick.
