The Nanz Company (Closed)
Based in New York with showrooms around the country, Nanz works closely with architects and designers to get their custom work just right, providing pretty much any custom hardware you can think of for your project. Highly professional—and armed with great aesthetics—we’d recommend them, and their work, for any restoration need. They also have a massive online catalog, which is an excellent tool if you’re looking for ideas. There’s also an appointment-only showroom in Soho.
