Southwark Metal 39AL_10IN Aluminum Vent Wall Cap 10 Inch

Product Description

The SOUTHWARK METAL 39AL_10IN is a 10-inch aluminum sheet metal vent wall cap hood with an integrated damper, designed for exhaust and ventilation termination applications at exterior walls. Constructed from aluminum for corrosion resistance, this wall cap provides a weatherproof termination point for round duct runs while the built-in damper prevents backdraft and outside air infiltration when the system is not operating. It is sized for 10-inch round duct and is installed by HVAC technicians and sheet metal contractors as part of residential or light commercial ventilation systems.

This wall cap is suited for exterior wall terminations on ventilation exhaust systems, including bathroom exhaust, kitchen ventilation makeup air, and general HVAC duct exhaust applications. The aluminum construction makes it appropriate for outdoor exposure conditions where moisture resistance is required. It is sized to match 10-inch round duct collars and is typically set into an exterior wall penetration, secured to the wall sheathing or framing, and connected to the interior duct run.

Key Features

• 10-inch diameter sizing for direct connection to 10-inch round duct
• Aluminum construction resists corrosion and outdoor weathering
• Integrated damper prevents backdraft and blocks outside air infiltration when system is off
• Hood profile deflects rain, debris, and pests away from the duct opening
• Meets ACCA and SMACNA applicable standards for sheet metal ventilation fabrication

Compatibility

Designed as an OEM-style replacement or new-installation wall cap for 10-inch round duct ventilation systems terminating through an exterior wall.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor in accordance with SMACNA duct installation guidelines and applicable local mechanical codes. Shut down the ventilation or HVAC system completely before beginning the wall penetration or duct connection work. Seal around the exterior flange with an appropriate weatherproof caulk to prevent water intrusion into the wall assembly. Confirm the damper swings freely and is not obstructed after installation before returning the system to service.
