American Metal Products 12C Universal Vent Cap 12 Inch Duct

Product Description

The American Metal Products 12C is an all-purpose universal vent cap constructed from aluminum, designed to terminate B-vent, exhaust, or general-purpose duct runs at a wall or roof penetration. The cap fits a 12-inch duct opening and measures 19 inches wide by 9 inches high, providing weather protection and backdraft resistance at the termination point. Its universal design makes it a practical stock item for HVAC technicians and sheet metal contractors handling a range of venting and ventilation applications. The aluminum construction resists corrosion and keeps weight low for overhead or rooftop installations.

This cap is suited for residential and light commercial applications where a 12-inch round or equivalent duct needs a finished, protected termination. Typical install scenarios include exhaust fan terminations, dryer booster duct ends, general HVAC supply or return openings, and gravity ventilation outlets. The all-purpose classification means it can serve multiple venting categories, reducing the need to stock separate specialized caps for different duct types.

Compatibility

Designed as a universal replacement or new-installation vent cap for 12-inch round or equivalent duct terminations in residential and light commercial HVAC and ventilation systems.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal contractors following local mechanical codes and manufacturer clearance requirements. Shut down the associated ventilation or HVAC system before cutting or modifying duct penetrations. Secure the cap per local code using appropriate fasteners for the substrate material, and seal around the penetration with a compatible flashing or caulk to prevent moisture intrusion. Do not install over active pressure-rated exhaust systems without verifying the cap is rated for that application.
