Keeps Out Rain and Debris – With Galvanized Steel Hat and Hood
Galvanized steel construction resists harsh weather and the hat-style hood prevents debris from entering HVAC ventilation. The hood sits over the pipe opening to block direct rain ingress while allowing exhaust to escape.
Reduced risk of blockages and weather damage protects flues, tumble dryers and stove pipes. Cleaner vents mean fewer maintenance visits and more reliable exhaust performance.
Promotes Efficient Airflow – Thanks to Round Vent Design
Round roof cap geometry is shaped to encourage steady exhaust flow and reduce turbulence that can cause backdrafts. The design channels air while providing an outlet that is sheltered from driving rain.
Improved draft stability helps appliances vent more effectively, making a noticeable difference for dryers and wood-burning stoves. Less backdrafting improves safety and performance.

Insertion diameter measures 4.88 inches (124 mm) with a flange depth of 1.18 inches (30 mm), matched to common 4.92 inch (125 mm) chimney pipes. A push-in fit is possible, with final security achieved using screws or clamps.
Snug seating minimises wobble and keeps the cap stable once installed, while a quick push-in fit speeds up installation. Final fixing choice remains flexible to suit on-site methods.
