Tilt latch search
As a matter of fact, our 26-243 and 26-244 do have round ends. Did you see all the pictures on their respective pages? I will post an example here for your convenience:
As you can see, the only square part of our latches is the top ridge, which does not affect installation whatsoever since it just goes over the top of the sash anyway. Do you think you could get these to work?
For future reference, most of our parts have multiple images available to view, all from many different angles so you can get a good idea of how the part looks. Please carefully examine all parts we suggest so you can be sure whether it's a match or not!
