Lambro Industries 343 Dryer Vent Hood Aluminum 3 in

Product Description

The LAMBRO INDUSTRIES 343 is a 3-inch aluminum dryer vent hood designed to terminate a residential dryer exhaust duct at an exterior wall or soffit. The hood provides a weather-resistant exit point for dryer exhaust, helping to keep moisture, lint, and heat from building up inside the duct run. A built-in damper flap opens under exhaust pressure and closes when the dryer is off, blocking backdrafts and pest entry. Licensed HVAC technicians and plumbers typically install this fitting during new construction or as a replacement on existing dryer vent systems.

This vent hood suits standard 3-inch round dryer exhaust duct installations in residential settings. It is appropriate for wall penetrations on wood-frame, masonry, or vinyl-clad exteriors. The aluminum construction resists corrosion in outdoor exposure and holds up to the heat generated by a typical residential dryer exhaust stream. Installers use this hood when replacing a damaged or missing termination cap or when completing a new laundry room rough-in.

Key Features

• 3-inch diameter opening matches standard residential dryer duct sizing
• Aluminum construction resists corrosion and heat degradation at the exhaust termination point
• Integrated damper flap closes when dryer is off to block backdrafts and pest intrusion
• Exterior-mount design suitable for wall or soffit termination on residential structures

Compatibility

Designed as an OEM-style replacement termination hood for residential dryer exhaust systems using 3-inch round duct.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician in accordance with local mechanical codes and the dryer manufacturer's venting requirements. Disconnect power to the dryer before beginning work, and confirm the duct run is clear of obstructions and lint buildup prior to securing the hood. Seal the perimeter of the wall penetration with an appropriate exterior caulk to prevent air and moisture infiltration. Do not install over an active exhaust without first removing the old termination cap completely.
