Our founder, Joseph Soss, built our company upon the bedrock of ingenuity and invention, evidenced by his creation of the groundbreaking concealed hinge more than a century ago. But his work didn’t end with innovative ideas alone; he saw his ideas through to quality production, tweaking and enhancing his products to meet his own high standards. This approach to quality control actually led to the development and patent of the SOSS die-casting machine, allowing Mr. Soss to address concerns over breakage with the original hinge prototypes. This spirit of innovation informing manufacturing lives on at SOSS today. From superior material selection through constant, on-going testing, SOSS hinges are manufactured to deliver better form, fit and function across a wide variety of applications and environments. And the best practices learned from more than a century of manufacturing exceptional hinges have been brought to bear with the production of our revolutionary UltraLatch entry handle, made in Pioneer, Ohio, USA.
