Latching Handle
Hello,
Your storm door hardware resembles the 40-177. This assembly has the same 1-3/4" hole spacing but we'll include all of the dimensions from our product page below. Take a look and let us know if you need anything else. Thank you!
Sure, look over the 40-150 turn handle shown below to see if this could work for your repair.
If you're referring to the keeper, unfortunately, we do not carry one for the 40-150 handle but you may be able to adapt the original keeper to work with the new handle if it is still in good condition. Keep in mind that modifications such as adding shims so that the keeper engages with the latch may be necessary.
