Good morning! Thanks for posting. I'm not quite familiar with that smaller, straight clip. It almost looks looks like its broken off of something larger. Can you confirm? If it is broken, could we see a picture of one that is undamaged?
Thank you for your patience in this matter. Unfortunately, after extensive research, we have been unable to come up with a substitute for this grid clip. I do not believe we will be able to help you with this project. I apologize for the inconvenience.
However, should we ever come across something like this, I will be sure to notify you the moment we have any information.
