Hi, I just moved into my first house and have been trying for a long time to figure out a solution to this gap in the UPVC French doors. I can't see any branding on the UPVC, only for the glass. I was recommended to look for something that fits on eBay however having scrolled through the listings I'm not confident enough with what I'm seeing. Would be really really grateful for any advice as to how to identify/fix this as I begin my DIY journey. Thank you in advance!
