The Guweta 4‑inch duct connector flange provides a versatile solution for residential HVAC and dryer‑vent applications. Designed as a square‑to‑round adapter, it bridges standard square wall openings to round ducts, creating a secure, leak‑free seal that improves energy efficiency and airflow. The flush‑mount wall plate features pre‑drilled holes and includes mounting screws for a quick, hidden installation.

Constructed from durable galvanized steel and finished in a clean white coating, this connector offers superior corrosion resistance and a modern look that blends with any interior. It is ideal for venting dryers, range hoods, bathroom fans, or any exhaust system, making it a reliable choice for both DIY projects and professional installations.
