Remove or relocate your Flettner roof ventilator with narrow base and professionally close the existing roof opening using this stainless steel blanking plate kit. This complete kit is designed to permanently cover the opening left after removing a compatible Flettner roof ventilator.
The kit includes an outer stainless steel plate and an inner stainless steel plate, together with matching gaskets and fixing components. It provides a neat finish on both the inside and outside of the vehicle roof.
The Flettner Narrow Base Blanking Plate Kit is specifically designed for the Flettner TCX-2 Narrow Base. This type of mounting base is particularly relevant to vehicles with ribbed roofs where available installation space is limited.
When converting a van, motorhome or enclosed trailer, it may be necessary to remove an existing roof ventilator.
This can happen when fitting a roof rack, changing the interior layout or moving the ventilation system to another position.
After the ventilator has been removed, an opening remains in the vehicle roof. It needs to be carefully closed to reduce the risk of rainwater, dirt and moisture entering the vehicle.
The Flettner narrow base blanking kit has been developed for this purpose. The combination of stainless steel plates and matching gaskets provides a neat roof finish when correctly installed.
Important: watertightness depends on the condition of the roof, correct installation and suitable sealing materials.
This kit is intended for the existing mounting opening of the Flettner TCX-2 with narrow base.
The TCX-2 is available with different mounting bases. The narrow version is particularly useful for roof constructions where there is limited flat mounting space between roof ribs.
A separate Flettner blanking plate kit is available for the standard base.
Always identify the original mounting base before ordering.
Compatibility with other ventilators, including certain F3000 versions, must not be assumed without checking the existing opening and fixing positions.
Part number I-BL-COM-NAR is intended for the narrow mounting base. Flettner roof ventilators fitted with a standard base require a different kit. Check the original base and fixing pattern before ordering. The two versions are not automatically interchangeable.
According to Flettner, this blanking plate kit is suitable for a maximum roof thickness of 4 mm.
This limit is essential for correctly securing the inner and outer plates with the two M5 locking nuts.
On vehicles with double-skinned roofs, insulation, additional reinforcement or roof headliners, the complete mounting structure must be checked.
Do not measure only the outer roof sheet if the fixing assembly also passes through additional layers.
Flettner specifies a maximum roof thickness of 4 mm. Do not use the kit on a thicker mounting structure without an expressly suitable installation solution. Both fixing points must be accessible and the gaskets must be correctly compressed.
The Flettner kit comes with two matching gaskets, one for the outer plate and one for the inner plate.
The gaskets help seal the connection between the stainless steel plates and the vehicle roof.
Flettner additionally recommends a suitable water-resistant adhesive or sealant to help minimise the risk of water ingress.
The sealant should be compatible with:
A suitable MS polymer sealant may be used when compatible with the materials and installation requirements.
Please note: successful sealing must be verified after correct installation and a suitable leak inspection.
Important: the Ø6 mm fixing holes are not the dimensions of the main ventilator opening. Always use the original installation template.
Installation must follow the official Flettner fitting instructions. The steps below provide an overview.
The narrow base kit uses two fixing points. On a TCX-2 Narrow Base installation, the existing small fixing holes are enlarged to Ø6 mm according to Flettner's instructions. Use the original installation template for any different opening. Never drill or cut based on estimated dimensions.
A suitable water-resistant sealant is recommended but has not been confirmed as included.
A roof ventilator is not supplied. This kit is designed solely to close an existing opening.
