All swing products are hinged using a weld on hinge. We custom manufacture our own design for these hinges to meet a number of needs unique to the steel products.
Each hinge will work for a lift off sash, but also the sash can be removed by unthreading the hinge pin. This allows for the sash to move straight out away from the frame. Many design conditions in today's architecture do not leave room above the sash for the lift off function. Each hinge has a small amount of vertical adjustment. Sometimes a small adjustment can solve a clearance issue, so we have included this functionality in our design.
Each hinge is supplied with a flat thread in finial. When desired we can produce custom shaped finials to replace the flat finial.
