Broan 634 Roof Cap, Rectangular, Steel/black, 8-inch

The Broan 634 roof cap is a durable ventilation accessory designed for use with Broan LoSone fans and bath ventilation fans. This rectangular steel cap with black finish mounts at your roofline to protect your home's exhaust system from the elements. The integrated backdraft damper and bird screen work together to maintain efficient ventilation performance.

The backdraft damper automatically closes when wind pressure tries to reverse airflow, preserving indoor air quality and reducing heating and cooling costs. The built-in bird screen prevents birds, insects, and debris from entering the ductwork, minimizing maintenance and keeping your ventilation system running smoothly year-round.
