I'm posting this on behalf of a friend. He has five of these protectors. They measure 122cm by 90cm and are knobbly on one side and smooth on the other. I think the tab is intended to fit in a doorway. They were headed to the skip until I intervened. I'm happy to offer them to the first person who responds and can pick them up in the next couple of days. If no takers they head skipwards once more.
Thanks for looking,
