When I measured my central heating outlets that I wanted to block I found the space I had to fill was a little bit bigger than the smaller block and somewhat smaller than the larger ones. I ended u[ buying an electric bread knife to cut the bigger ones down to size. I was happy with the result and now I slice my bread with the electric knife.

We decommissioned our gas central heating and these have stopped the draughts coming up from the ducts. Cant believe more companies are not selling them. :)
