The Soss Quadrant Hinge
Ideal for Humidors and Jewelry Cases
Constructed of solid brass, the SOSS Quadrant Hinge is now available for woodworkers or
manufacturers of high quality wood products. The hinge is inlayed into the case or frame
making it absolutely invisible when the case is closed, yet good looking when open.
Available in either a high polish brass or bronze finish, the SOSS Quadrant Hinge adds
a custom touch to that special wood project.
