Items dispatched by courier tracked in ZONE DA in the picture. I have added some pictures how we fit this vent as we dont screw down from the outside of the van. Angle and roof profiles are not included. A 28cm x 28cm Fiamma roof vent recommended for small rooms such as bathrooms, showers, or kitchens in motorhomes, caravans, van conversions and campervans. Discreet in design, this slim framed skylight provides permanent ventilation and has a UV resistant white cover. It is supplied with an integrated aluminium mosquito net that can be removed for easy cleaning. Thanks to the’sandwich’ mounting system, this roof light can be installed without having to drill any additional holes in the roof of the vehicle. The rooflights aerodynamic design means it does not need to be fitted with a spoiler and noise and vibrations are greatly reduced. Please feel free to ask any questions. We also sell many other conversion parts please view my other listings.
