Telescopic Underfloor Vent Black 220mm x 215mm
Should do nicely
I bought this to get some ventilation into the rear of the cellar. It seems sturdy enough, hopefully it'll help.

FITTING AIR BRICK VENT
have bought a few of these now .the product is fine. however a word of warning these air brick channels are not suitable for old houses with 68mm width of bricks or more or brick cavity larger than that in new build houses. I have fitted these to a 1994 semi with cavity walls. problem is the front air brick vent will not fit flush with the exterior brick work ,they will be sat inside the opening by about 2cm. the solution is which is a rather messy one is to grind back the inner face of the exterior brick by 2cm .you will need to take out the inner bricks first. I did this and now they are ok but its a lot of work and dust , not for the faint hearted tand you need a face mask and goggles if you grind back your bricks . and a dust sheet .

Ex-Stock & Good Design
Building an extension so needed to extend the airflow under the new concrete floor.
This was just the thing and was able to collect them straight away from the local store.
- As we needed to extend rather than just drop the air vent it would of been useful if there were adapters to convert from rectangular to 110mm round pipe.
But overall a good product at a reasonable price.

Fitted these to a building where the Highways Dept. in their wisdom put a new path outside the house and half covered over the air brick creating a drain into the house. these did the job, better quality that some I have used in the past.
