The New York collection from Nostalgic Warehouse features Craftsman styling, popular in the 1920's and 1930's, and often one of the hardware choices in Sear's Craftsman Kit homes. This collection is characterised by it's simple and straight yet elegant lines, and works well across several transitional styles. The style has been modified slightly to fit on modern pre-drilled doors. The interior half only option is to be ordered in conjunction with an "exterior handle only" door set. This option is made available for those who want a different style or finish on the interior and exterior of their entry door. A double cylinder will have two keyed deadbolts (one interior, one exterior) while a single cylinder will have one keyed deadbolt (exterior) with a thumbturn on the interior.
