The Studio Short Plate is a great choice for interior doors that favor clean lines and understated detail. At 4" x 2-½" , it offers more presence than a round rosette while maintaining a simple, balanced profile. Made from solid brass, it provides strength, weight, and everyday durability. Combined with the Black Porcelain door knob, featuring a smooth round shape and glossy porcelain surface, this pairing delivers bold contrast and vintage charm to interior doors. Crafted with a forged brass base and durable porcelain construction, it offers lasting performance for bedrooms, bathrooms, and traditional living spaces. Nostalgic Warehouse door hardware offers premium interior and entry door sets crafted from solid forged brass, blending authentic period design with lasting durability for traditional, vintage, and restoration-style homes. Our interior door knobs and lever sets are available in multiple finishes, delivering timeless style with versatile design options for every space.
