Lambro Industries 577237 Aluminum Wall Exhaust Hood Vent

Product Description

The LAMBRO INDUSTRIES 577237 is an 8-inch aluminum wall exhaust hood vent with a 6-inch tail pipe, designed for through-wall exhaust termination in residential and light commercial ventilation systems. Built from 22-gauge aluminum, the unit resists rust and holds up to repeated use in humid exhaust environments. A spring-controlled damper allows unrestricted airflow when the system is running and closes to block back drafts when the fan is off. HVAC technicians and general contractors install this cap as the exterior wall termination point for exhaust duct runs.

This wall cap is suited for bath fan exhaust, range hood exhaust, and general ventilation applications where conditioned or stale air must exit through an exterior wall. The 6-inch tail pipe connects to standard round duct and the 8-inch face plate covers the wall penetration at the exterior surface. It is appropriate for residential construction and renovation projects where a clean exterior termination with back-draft protection is required.

Key Features

• Spring-controlled damper prevents back drafts and air infiltration when the fan is off
• 22-gauge aluminum construction resists rust for long service life
• 8-inch face plate with 6-inch tail pipe fits standard round duct connections
• Suitable for bath fan exhaust, range hood exhaust, and general venting applications
• Through-wall installation design for exterior wall termination

Compatibility

Designed as an OEM-style replacement or new-installation wall cap for residential bath fan and range hood exhaust systems using 6-inch round duct.

Installation Notes

Installation is typically performed by a licensed HVAC technician or general contractor. Power to the connected exhaust fan must be shut off at the breaker before beginning work. The tail pipe should be sealed to the duct collar with approved foil tape or mechanical fasteners to prevent air leakage at the connection. Check local building codes and the applicable mechanical code before installation, as exterior penetration requirements and clearances may vary by jurisdiction.
