Larson Storm Door sash Lock

A landlord from AR - Arkansas says:
I have a larson storm door sash lock . I need a replacement can you help me find one

It's total length is 2-1/8 x 1/2 inch. If the new one is longer that is fine I just can't have it wider than the 1/2.

We unfortunately don't have an exact match for this lock. The closest product in our inventory would be the 90-272 , but this is a lot wider at 13/16" compared to yours, which looks to be around 3/8". Even if you had room on the frame to install the larger lock body, you still have to account for hole alignment, which would be off with the larger lock body. In other words, because the body of the lock extends so much further out from the holes, the sweep itself wouldn't properly engage with the keeper.

I am very sorry that we cannot offer a better match. These older, skinny locks are just not available to us at this time.
