Lock Body for Pella Storm Door

A quick learner says:
I ordered a Lock and Handle set from another supplier for a Pella storm door. It did not come with a Lock Body. The number of the handle hardware kit is 33251. What lock body do I need to order?

Thanks for writing in. I'm afraid I can't narrow down that code to any specific part. I am not sure if we're going to have what you need, as Pella hardware can be tricky to replace; but to be safe, show us a picture of the lock body in question, and I'll do my best to see if we have something that can work for you.

A handy person from McDaniel, Maryland says:
Hi,

I checked the number on the door. It's 90566 321 111003

I've also attached a picture. I think I should order part number 40-191. Just want to check before I place the order.

I agree, the 40-191 Pella Storm Door Mortise Lock looks like a match to me. Just be certain all the dimensions we list align with your old hardware.
