## Overview

The Lambro 143W 4-inch Plastic Soffit Exhaust Dryer Vent features a robust damper that prevents outdoor debris, insects, and air leaks from entering your vent system. Designed for easy, no-assembly installation, its durable plastic construction resists sun and sea air damage, making it ideal for both coastal and inland homes. Perfect for clothes dryers and soffit ventilation, this vent combines practical durability with energy-smart performance.

## Description

This 4 in. Plastic Under-Eave Vent from Lambro is an industrial-strength damper that prevents outside elements from entering your vent at home. It can also be used for your dryer to keep dust and dirt particles out of your clothes.

## Features

- The Lambro 4" white plastic soffit exhaust vent is ideal for venting through the soffit.
- The vent features an opening and closing damper that prevents outside elements and air from entering. The damper seals the vent opening when the clothes dryer or bath fan is not running because no exhaust air exits the vent.
- When the clothes dryer or bath fan operates, the exhaust air pressure pushes the damper open to let the exhaust air escape from the vent.
- You can easily use the exhaust vent for new and replacement installations over an existing 4" opening. The vent frame comes with four screw holes to secure the vent and a caulk-friendly frame for completing the installation.
- The vent’s manufacturing material is polymer resin with a UV additive to prevent premature fading caused by sunlight. It would be best to prep the vent before painting it; we recommend plastic paint to paint the plastic vent effectively.
