"Demon Stripes install" ???????

The only one I have loaded

That's okay, I think I can see enough of the key lock opening to prove my theory. I centered the opening in the stripe with the key lock opening, and that's the way your picture appears to me as well, centered over the key lock opening. So, it seems my stripe was not cut correctly because if I lower the top to meet the measurement you're showing the stripe will cover the upper part of the key opening by about 1/8". Thx.
