Hello! These are definitely old Andersen brand latches, but I actually don't think that this exact design is made anymore. I think the best modern replacement is going to be the 70-226. This is also a genuine Andersen part and even has the same general design. The only major difference is the locking tab. Look it over and see if you think you could still get this to work in your frames. Dimensions for 70-226
