Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose the 634 when your fan's duct run exits through the roof and is either 3-1/4 in. x 10 in. rectangular or up to 8 in. round. For wall exits, Broan's wall caps are the appropriate alternative. Seal the cap's flange to roofing material with an appropriate roofing sealant and follow the manufacturer's installation guide for weather-tight performance.
Work on roofs presents fall hazards; use proper ladder and fall protection and follow local codes when penetrations are made.
