Replacement storm door latch

A quick learner from Maryland says:
My storm door was new about a dozen years ago. Recently I discovered that the latch had become twisted and that was the reason the door wouldn't stay closed without locking. Lock is not integrated with latch. I don't know how the twisting occurred but while the rest of the assembly appears to be metal, I think the latch itself is not. It's thick, but might be plastic, resin, or something. Even in angles form, edges are not especially sharp.

Screw holes are approx 1 3/4 apart for both latch and lock. Hole through which latch operates is approx 1 1/4 by 1 3/4.

Inside, latch is operated by push lever, outside is operated by knob.

I want to replace the latch assembly, and would be okay with replacing lock assembly as well if it comes with, although that's not absolutely necessary.

I'm reasonably handy around the home and can follow good directions.

Thank you for any assistance you can provide.

Thanks for posting. I've seen this handle before. We don't carry it, but we still may be able to offer a solution. What I've done in the past is use our 40-145 latch. I also shim it up with our 40-179 so that it builds the latch up to the height needed to catch the keeper.

I appreciate your response to Md above. I need to replace 2 of these old latches for my in-laws.

Do I only need one shim per latch to get each of them to the right height?

If our outside knob still functions, can I use it with this new latch?

Thank you.

I suggest using one or two 40-179 shims. One might be enough, but you might want to order two to be safe.
