127mm BLACK HOLE VENTILATOR C/W FIXED ANTI-DRAUGHT BAFFLES - K-BM725

This is a top class product done the job spot on. I have more ordered.

It works and was simple enough to fit. It obviously still lets the air through, we have a back boiler so the airflow is needed. It has stopped the wind blowing straight into the house we used to be able to feel a cold draft when the wind blew a certain direction and force. This has solved the problem. Highly recommend.

The item was correct but when the old vent was uncovered it was not the correct width

Used these for years now , always great

Vent for outside

Had just a hole in in my vent so bleeze was flowing through. Crap building from property boom. This does a decent job although bit expensive for some plastic. Get some expanding foam to fill in the gaps if its to small. Cheaper option and better is buy the foam tubes for the pipes in the attic. Stick three in the hole cut the ends off and done. Air still gets in and out but not to much and cheap as chips.

This vent was used to provide a vent for a log burner we recently installed. There is little or no draught. Fitting was easy and it isn't unsightly. Delivery was prompt and we can recommend both the supplier and the product.

The baffles don't work completely, however there's not a big draft.
