The Fiamma Rooflight Vent 40 Crystal is a 400x400mm manual roof vent that brings natural light into your caravan or motorhome without turning the place into a greenhouse. The translucent tinted dome filters daylight nicely while keeping direct sun glare down, and there's a fixed airflow channel running through it so you get constant ventilation even when it's closed. That's genuinely useful if you're parked up and want fresh air without leaving the thing wide open. The handwheel operation is straightforward, and a centre support arm holds the dome at whatever angle you set it to. An aluminium mosquito net sits below the dome, so insects stay out while air moves freely. Fiamma's patented rubber seal does a proper job of keeping rain out, and the aerodynamic profile means you don't need a separate spoiler fitted on top. It's built in Italy, weighs 2.8kg, and meets TUV and ABE safety standards.SPECIFICATIONS• Brand : Fiamma• Type : Roof Vent• Size : 40cm x 40cm• Weight : 2.8kg• Approvals : ABE approved• Application: Caravans, Motorhomes, Van Conversions• Country of Origin : Italy.
