Southwark Metal 39al-10 Aluminum Wall Cap Damper 10in

Product Description

The SOUTHWARK METAL 39al-10 is a 10-inch aluminum wall cap with an integrated damper, designed for exhaust and ventilation duct terminations at exterior wall penetrations. The cap protects the duct opening from weather, pests, and backdrafts while the built-in damper opens under airflow and closes when the system is off. Fabricated from aluminum, the unit resists corrosion in outdoor installations. HVAC technicians and sheet metal installers fit this type of fitting as a final termination point for exhaust runs in residential and light commercial ventilation systems.

This wall cap is suited for exhaust duct systems terminating through exterior walls, including bath exhaust, dryer exhaust, kitchen range ventilation, and general HVAC exhaust applications. The 10-inch throat size accommodates standard 10-inch round duct runs. It is installed at the exterior wall surface, making it visible from outside the structure, and is appropriate for both new construction and replacement work.

Key Features

• 10-inch throat diameter fits standard 10-inch round duct
• Aluminum construction provides corrosion resistance for exterior installations
• Integrated damper closes when the ventilation system is not running, blocking backdraft and pests
• Wall-mount design for through-wall duct terminations
• Suitable for residential and light commercial exhaust applications

Compatibility

Designed as an OEM-style replacement or new-installation wall cap for 10-inch round duct exhaust systems in residential and light commercial HVAC, bath, kitchen, or general ventilation applications.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Power down the ventilation equipment before connecting or sealing the cap at the wall penetration. The cap should be secured to the exterior wall surface and sealed with appropriate weatherproof caulk to prevent water infiltration. Verify local mechanical code requirements for exhaust termination clearances and damper operation before completing the installation.
