A hinge assembly containing a receiver member having a corrugated inner surface and a locking pin for being pivotally disposed within the receiver portion about an axis. The locking pin and receiver member have complementary corrugated engaging surfaces that allow the hinge to provide support for a cantilevered structure when the pin and receiver are engaged. When the complimentary pin and receiver are disengaged, the pin member can be incrementally rotated so as to allow the cantilevered structure to be positioned in a different position or orientation.
