Williams Furnace Company 6801 Rear-Outlet Register for Forsaire Top-Vent Furnace

With the addition of a rear outlet register, you can add heat to a rear adjacent room. The finished wall of the second room must be within 10 inches of the furnace. Everything you need, the rear outlet register, a 10" boot and a damper, is included to heat the second area. The built-in damper lets you shut off the air flow to the second room if desired.
