Until about 1930 there was a proud history of hardware in America. Hundreds of small factories made an enormous variety of creatively designed products. Craftsmen from many disciplines devoted their energies to making locks that provided both function and beauty. Unfortunately, during the depression many of these factories failed, and then during WWII brass became scarce and lock designs were reduced to the bare essentials. In more recent years the emphasis on cheap, high volume building products has discouraged manufacturers from re-introducing well made hardware. But now these ideas are changing, Americans are re-discovering the satisfaction that comes from owning well designed products. Emtek's mission is to make it possible for home owners to apply these higher expectations to door locks. We are striving to provide a broad, interesting range of products that consumers can use as elements of decor, not just as a way to latch a door.
