Thank you for this site and for the option to post questions. I have twin seal single hung windows that have "MW" stamped on the latch. I'm not the original owner of this home that was built in 2001. Today there was a loud noise and I found the clip latch that creates spring tension broken at the top. It looks as if 26-200 screw plug and ss screw are what I need. I also need the seals for these windows. I've attached photos. Please verify the parts I need. While I see no condensation between any panes, I see the plastic parts are cracking, probably due to UV over time. Given the age of the windows, do I need to be thinking about replacement? Thanks for your help with this.
