Larson screen door replacement latch needed

A home owner from Laramie Wyoming says:
The attached photos are of the Larson screen door latch that the spring no longer works to lock the door shut so the handle just hangs down. I ordered a mortise latch off your website that had the exact same external measurements as this latch but when we removed the damaged latch, the opening for the door handle and lock bolt were different. The door handle opening needs to have 5 sides, not square, and looks like an X opening for the bolt lock. There is also a little metal bracket at the bottom of the latch that hooks onto the bottom of the opening on the screen door where this latch is inserted. I just returned the latch I originally bought off your website so you should have record of what that one was because the measurements did match. However, there were different model letters stamped on the side. The latch we need is model stamped DG and the wrong latch we received from your website had DAA stamped on it instead. I'm hoping you have that model DG, but I haven't been able to find it on your site. Please help if you can. Thank you!

Thanks for posting. I see your dilemma. I think you're only choice may be to go with the 40-198 , but then also replace the handle set with something that can work with the difference in the keyway shape. Now, there's no one specific handle set to go with the 40-198 , but I find that the 40-199 works perfectly well. I'm just not sure how well it matches up to your old handle, in terms of how it mounts to the door. You may end up having to drill new installation holes for it. Just something to consider.
