Hardware Concepts

Our mission at Hardware Concepts is providing high-quality door hardware to designers, builders, and homeowners. 


542 Lighthouse Ave. Ste 111, Pacific Grove, CA 93950


Since the beginning, INOX has been dedicated to providing exceptional customer service along with creatively designed door hardware.

Unison Hardware, Inc., began in Germany in 1991 and has since established three manufacturing factories in China; in 2005 Unison began developing and marketing its INOX brand for the North American Building Markets.

While our core business in Europe has focused on OEM manufacturing for the leading brands in the EU market, in the U.S. we began developing our own line of products. At the 2006 DHI tradeshow, Unison launched our INOX residential line and at the 2006 International Builders Show, we debuted our commercial line.

The material used to create INOX product is genuine 304 grade ANSI certified Stainless Steel with finishes in US32 and US32D that will last a lifetime. We pride ourselves on high quality Stainless Steel door levers and accessories, as well as Oil Rubbed Bronze (US10B), a classic touch on a contemporary design, plus Graphite Black (19G) and now, we’ve added a ceramic coating facility in Sacramento, allowing us to offer gorgeous, abrasive-resistant Ceramic Graphite Black, Ceramic Flat Black, Ceramic Stormy Grey, Ceramic Dark Bronze, and other finishes.
