The SOSS name has been a staple in the functional hardware community for quite a long time. The SOSS invisible hinge was invented by Joseph Soss after tripping over a protruding hinge on a ship deck. He quickly developed a concept for what would become the first concealed hinge in 1902. Shortly after in 1903, a patent was secured. Since its inception the SOSS invisible hinge has had many uses and is the industry standard for concealed hinges. It has been used in the Buckingham Palace, the White House, Disneyland, countless hotels, offices, government buildings and healthcare facilities. The elegant, modern look and smooth operation set this hinge apart. The fully concealed hinge allows for utmost security as a seamless look is created and pins cannot be tampered with.

The SOSS Difference

The main difference is that the moving pivot point remains inside the hinge during travel, eliminating an external pinch point on the back side of the door. When closed, the SOSS invisible hinge cannot be seen or tampered with. When open, the riveted hinge pin is non-removable. This makes the hinge ideal for high security areas.

SOSS invisible hinges are selected for use in an endless array of specialty applications where compact size, smart operation and superior appearance are required. Hinges are now offered in various finishes like Satin Nickel, Satin Chrome, Satin Brass, Oil Rubbed Bronze, White E-Coated, Black E-Coated and more. SOSS offers hinges in various sizes to accommodate any project and has also developed fire rated hinges for both wood and metal doors.
