Fenestra bi-fold door replacement parts

A home owner from Kensington, Maryland says:
In the video, there are square holes on the door for the catch and for the clamp but my doors have a round hole as shown in a photo attached. There is no information about the doors except for the one sticker in a photo attached. I have 2 bifold doors that are missing all the top and bottom pins. So I think I need 4 of 21-001, 4 of 21-007 and 4 of 21-154 but not sure they will work.

Thanks for posting. It's tough to say, your setup is a little odd. Going based on your two pictures, our 21-018 and 21-019 look like they might match up, but I'm not sure. Look them over and see what you think.
