Clip to secure my storm door glass

Thank you for reaching out to us. We used to sell this clip but it was discontinued and no longer available, unfortunately. I suggest taking a look at the 70-092 offset Z-clip along with the 33-104 machine screw. I believe this would make a good replacement for your existing clip. Take note you will need to open up the mounting hole in the 70-092 to allow the screw to pass through it. You can try using a "rat tail" file to open up the hole. Just note that modified items cannot be returned for a refund. Take a look at the specifications for these parts and see what you think.
