It’s frustrating, but I actually think the whole “integral part” thing isn’t always just about planned obsolescence or cutting corners. Sometimes, it’s a structural choice—especially with tilt windows—where making the latch or balance spring replaceable would mean bulking up the frame or compromising the seal. That said, it’s still annoying when a $2 part turns a whole sash into landfill. I wish more manufacturers offered at least some kind of retrofit kit, even if it’s not perfect.
That makes sense, though it still bugs me when a tiny broken bit means tossing the whole window. I had a similar issue with a 90s casement—just needed a new crank, but it was all sealed in. Has anyone actually seen a retrofit kit that works well, or is it mostly DIY hacks?
