FIAMMA WHITE HATCH 400mm x 400mm

The Fiamma 400mm Roof Vent is a classic, fan-free roof hatch designed to provide reliable ventilation and natural light for caravans and motorhomes. Operated from inside via an easy-to-use winding mechanism, it hinges open smoothly to allow adjustable airflow while keeping a low profile when closed (just 85mm above the roof).

This vent is designed to fit the European-standard 400mm x 400mm ceiling cut-out, but with some modification it can also be adapted to fit 360mm openings, making it a suitable replacement option for many USA-style hatches. Constructed from UV-ray resistant materials and featuring permanent ventilation, it helps reduce condensation and stale air inside your RV living space.

Finished in white both inside and out, and supplied with internal trim and flyscreen, this Italian-made vent offers a clean look and dependable performance for touring and long-term use.
