certainteed double hung window sweep lock (latch)

Thanks for writing in. For a Certainteed window lock, our 90-161 might work. It won't have the alignment nubs on it, though, so you'll need to also use the keeper that comes with it. Just double-check the hole spacing dimensions to ensure they match your old part. Ours is 2-1/16" with a 7/16" offset.
