Dual colors can be achieved by specifying different finishes for the exterior face covers and interior mullions. A unique split vertical mullion for straight-in installation of each bay, special perimeter members for easy anchorage and the option to shop install is achieved with screw spline assembly.

Key Features:

  • Vertically butt glazed
  • 2-7/8" (73 mm), 4" (101.6 mm) & 5" (127 mm) back member depths
  • Exterior glazed
