The 3/8” tempered glass used in Symphony Hinged Frameless Doors is very heavy. A typical door weighs in excess of 70 pounds. The glass and the glass panel are packaged in separate boxes with multiple layers of protection. Since these products can only be shipped and delivered by commercial freight carriers, the outer cardboard layer may be scuffed, slightly torn, etc. in transit. If the door and/or panel is not damaged there is no need to replace the unit.
