I recently installed a dog door panel for my sliding patio glass door. The way the dog door was made I had to install it centered in the patio door channel vs flush with the sliding glass door. This has created a problem that doesn't allow me to install the hinge that will lock the door closed. There is a good 1/2 inch difference in height.
I'd like to make a shim or something to raise the hinge placed on the dog panel to be flush with the sliding glass door. I'll need to be able to drill through the object to anchor it into the dog panel. I've never created something like this and I'd like to hear if anyone has some suggestions on how to proceed.
