Advice for Finding a Replacement Part for Window
My home has very average/middling quality vinyl windows...the latch part that holds the window closed is pretty much all plastic, and I doubt they will survive 5 years. My old home (see pic) has metal latches in original windows that have held up for life of the home, currently ~29 years old. I'd like to replace my plastic latches with metal ones like these. Is this feasible?
I guess there are two practical considerations:
-1) How are latches on new vinyl windows attached? with screws or something more permanent like a bolt+nut needing access from inside window?
-2) If feasible, where can I source these better latches from? I'd need to identify them specifically, I expect. At the moment I am not sure of the window brand.
lol...looks like I can't post a pic, but here's a Dropbox link if seeing what I am talking about helps:
Edit: looks like the windows are "Ply Gem":
