Southwark Metal 39AL_6IN Vent Wall Cap Damper 6 Inches

Product Description

The SOUTHWARK METAL 39AL_6IN is a 6-inch aluminum sheet metal exhaust vent wall cap with an integrated damper, designed for use in residential and light commercial ventilation applications. Constructed from aluminum, this wall cap provides a durable, corrosion-resistant termination point for exhaust duct runs that pass through exterior walls. The built-in damper prevents back-drafting and blocks outside air, pests, and debris from entering the duct system when the equipment is not in operation. HVAC technicians and sheet metal contractors install this cap as the exterior termination for exhaust ventilation systems.

This wall cap is suited for 6-inch round duct exhaust applications including bathroom exhaust, kitchen ventilation, dryer venting, and general HVAC exhaust terminations through exterior wall surfaces. It is manufactured in compliance with ACCA and SMACNA standards, making it appropriate for installations where adherence to recognized sheet metal and air conditioning industry guidelines is required. Its aluminum construction holds up well in outdoor exposure conditions without rusting.

Key Features

• Integrated damper prevents back-drafting and blocks outside air intrusion when system is off
• Aluminum construction resists corrosion and is suitable for outdoor exterior wall installation
• 6-inch size fits standard 6-inch round exhaust duct terminations
• Compliant with ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style replacement and new-installation wall cap for 6-inch round exhaust duct systems in residential and light commercial HVAC, bathroom, kitchen, and general exhaust ventilation applications.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Shut down and de-energize any connected exhaust fan or air-handling equipment before beginning work. The wall cap should be sealed at the wall penetration with appropriate weatherproof caulk or flashing to prevent water intrusion. Reference SMACNA duct construction standards and local mechanical codes for proper fastening and clearance requirements at exterior wall terminations.
