Fitting InstructionsThe Flettner Slimline roof vent is their newest addition. It’s a very low profile van roof vent which makes it ideal if you have roof bars or a roof rack fitted. It’s defined as the lowest van roof vent in the World and has the shortest installation time.
When Flettner designed the Slimline roof vent, they had the perfect balance of an aesthetically pleasing design and superb functionality. Fitting the Flettner Slimline couldn’t be any easier. It comes with four M5 bolts that secure the shutter on the inside of the van roof.
For vehicles which have an inner lining, a Flettner Slimline adapter is available to bridge the gap between the outer skin and the inner lining.
Fitting The Flettner Low Profile Roof Vent To Ribbed Roofs
If the ventilator is to be to a ribbed section of a roof ensure that the base of the ventilator can sit on the roof rib, and that the position chosen will permit the shutter to the underside of the roof. The Flettner Slimline ventilator cannot be fitted to roofs where the raised ribs are less than 2.6” (66mm) wide.
