Remove or relocate a Flettner roof ventilator and neatly seal the existing roof opening with this stainless steel blanking plate kit for the standard base. The kit is designed to permanently cover the opening left after a compatible Flettner roof ventilator has been removed.
The kit includes an outer stainless steel plate and an inner stainless steel plate, complete with matching seals and fixing components. This provides a neat finish on both sides of the vehicle roof.
It is intended for suitable Flettner 2000 and TCX-2 roof ventilators fitted with the standard base. Compatibility with other versions, including certain F3000 configurations, must be verified before installation.
During the conversion or refurbishment of a van, motorhome or trailer, it may be necessary to remove a roof ventilator or install it in a different position.
This may be due to a new roof rack, solar panel installation, changes to the vehicle interior or a different ventilation arrangement.
Removing a roof ventilator leaves an opening in the vehicle roof. That opening must be properly closed and sealed to reduce the risk of water entering the vehicle.
The Flettner standard base blanking plate kit is designed for this purpose. Its stainless steel plates and matching gaskets provide a neat way to cover the opening when correctly installed.
Important: the final watertightness depends on the roof construction, correct installation and suitable sealing materials.
This kit is designed for suitable Flettner roof ventilators fitted with a standard mounting base.
For other models, check that the existing roof opening and fixing hole positions match the standard base configuration.
Please note: the Flettner TCX-2 is also available with a narrow base. A different blanking plate kit is required for that version.
Before ordering, check which mounting base is fitted to your existing Flettner ventilator. Part number I-BL-COM-STD is intended for the standard base. Compare the roof opening and fixing positions with the official installation instructions.
The Flettner standard base blanking plate kit is suitable for existing roof openings up to Ø105 mm.
The maximum permitted roof thickness is 4 mm, according to Flettner.
These limits are essential for correct mechanical fastening of the inner and outer plates.
Where a vehicle has a double-skinned roof, additional reinforcement or a roof lining, check the complete mounting arrangement before installation.
This kit is intended for openings up to Ø105 mm and roof thicknesses up to 4 mm. Do not use it on thicker roof constructions without an expressly suitable installation solution. All four fixing points must also be correctly positioned and accessible.
