Broan-NuTone RVK1A Roof Vent Kit, Black - 3 to 4 in Duct

Overview

Enhance air movement in compact living and working areas with the Broan-NuTone RVK1A Roof Vent Kit in black. This versatile vent cap is designed for easy installation and works with either 3" or 4" ducting, giving you installation flexibility whether you’re upgrading an existing vent or adding one to a new space. A thoughtful blend of form and function helps you breathe easier in bathrooms, rec rooms, home gyms, or other well-used rooms.

What makes the RVK1A stand out

The cap includes a back draft damper and a bird screen, which work together to minimize outside air entering the living area and to keep birds and small pests out of the duct line. This combination supports calmer operation and cleaner airflow paths in environments that cycle air frequently or see humidity and dust.

Designed for straightforward installation, the kit comes with essential components to get started, including an integral 3" to 4" adapter for duct versatility. The flexible ducting included is built to meet recognized standards for safe, reliable connections in residential settings.

Use cases

Great for bathrooms, rec rooms, or home gyms where steady ventilation can improve comfort and reduce lingering odors. The included adapter helps you adapt the kit to your existing ductwork without a full retrofit. While it supports efficient air movement, this vent kit is not intended for all applications, so plan placement with roof pitch and weather sealing in mind.
