Product review (5 stars): Good quality
I'm a remodeling contractor and use frequently use this vent cap for my new bath fans. The steel construction is strong and sturdy. The built in damper prevents backdrafts and pests from entering. It can easily be spray painted to match exterior house color. I rarely use the provided foil flex duct. I prefer to use insulated ducting to prevent condensation due to the conditioned air of the bathroom and unconditioned attic air temperature.
