Buying Guide

Match vent diameter to ducting

Measure your existing duct or roof opening and choose a 6- or 8-inch vent to avoid modification and ensure proper airflow

Prefer metal construction

Galvanized or stainless steel resists corrosion and holds up better than plastic in harsh weather and high-moisture areas

Check for a functioning damper

A spring or ball damper prevents backdrafts and pests when the fan is off, improving energy efficiency and comfort

Consider removable or kit designs

Removable caps or vent kits simplify installation, maintenance, and winterizing without needing full roof access

Verify roof compatibility

Confirm flashing type and roof pitch compatibility to ensure a watertight seal and straightforward installation
