Ha I'm using that from no-bslures. Really like it over the aluminum except for it seems to want to crease over by dog. Any pointers on how to fix that?

Are you cutting a notch at the dog so it can fit under the jaw? Do you have a picture? Maybe that will help to understand how it is creasing.

I misspoke. It's on a Dogless Bridget. Creasing by where dog would be

If you poke a starter hole in the screen then force it over the pan/dog notch before setting it helps. I stick my thumb under the pan and using the other hand I first pull the screen towards the loose jaw then crease the screen on the sides of the pan.

I cut the pan cover 1/4 inch wide slot so the cover goes below the dog-(less) jaw on my Montana #3s. It’s been working fine. Make that cut an inch or so deep.

You could try the Mullins modification. Make two slits in the screen and slide it onto the pan. No bubble - no creases
