Mine is called Invis a Grip, there is enough of it in the package to take care of many rulers. It doesn't have to go completely to the edge, I left it 1/2" in all of the way around the edges.
Thanks for the suggestion. I just found several websites that sell the Invisa-GRIP. It should help me a lot!
