This VMI (Air-Pro) roof cap is the exterior termination fitting that caps the duct run from a kitchen range hood at the roofline, closing off the duct opening and protecting it from weather and backdraft.
A ducted range hood moves cooking air out of the kitchen and pushes it through a duct run to the outside. The roof cap is where that run ends. Installed at the roof surface, it covers the duct opening so rain, wind, and small animals cannot enter the duct when the ventilator is off, and it allows exhaust air to exit freely when the system is running. Without a properly fitted cap, the duct terminus is exposed, which can compromise both performance and the roof structure over time.
This cap is sized for an 8-inch duct connection, which matches the exhaust outlet on Air-Pro ventilator units designed for larger cooktop installations. The product name references both 10-inch and 8-inch cap sizes within the VMI 5077 product family, so confirm the duct diameter at the installation point before ordering to ensure the correct size ships. VMI produces this component specifically for the Air-Pro line, so it is engineered to the tolerances of that ventilation system rather than being a generic aftermarket fitting.
This roof cap is the right choice for a kitchen installer or cabinet shop finishing a ducted range hood installation where the duct exits through the roof rather than through a wall. It is also the correct replacement part for an existing Air-Pro installation where the original cap has been damaged or is missing. Homeowners renovating a kitchen and routing new ductwork overhead will need this cap to complete the exterior termination before the hood is operational.
This is a roof cap, designed to terminate the duct at the roof surface. For a duct run that exits through an exterior wall, a wall cap is the appropriate fitting instead.
This cap fits an 8-inch duct. The VMI 5077 family includes both 8-inch and 10-inch sizes, so confirm the duct diameter at your installation before ordering.
This is a VMI component produced for the Air-Pro ventilator line. Compatibility with other brands depends on whether the duct diameter and fitting style match. Verify dimensions against your specific installation before specifying.
No. This is the roof cap termination fitting only. The Air-Pro ventilator, ductwork, and any other installation components are separate purchases.
Specify this VMI roof cap to finish an 8-inch ducted range hood installation at the roofline, with a fitting built for the Air-Pro system and sized to close the duct opening against the elements.
