Inspired by the American Arts & Crafts movement of the early 1900s, the rugged design and hand-hammered details of the Craftsman Entry Set emphasize handwork over mass production. The Round Clear Crystal knob features a circular shape that magnifies the beautiful facets underneath. The single-cylinder deadbolt features top-quality internal components for smooth, long-lasting operation. All Nostalgic Warehouse products are made from solid forged brass for durability and beauty.
