Will your replacement mortise latch, part #40-198 fit my Larson Storm Door. See attached pictures of the door model/serial numbers and pictures of the existing lock set.

I look forward to your reply.

P.S. Is the latch reversible for either a right or left swing door?

The 40-198 is reversible, yes, but I'm afraid I can't confirm if it will fit in your door. That will come down to dimensions. We list detailed measurements on the 40-198 store page that you can use as a reference. You have to measure your original to confirm that they all match up.

All of the external dimensions are identical to those shown on 40-198. I have not disassembled the lock set to verify the internal dimensions such as the depth of the mortise as well as those between the latch and the deadbolt. However, I will assume the new part will fit, so I have placed an order for part #40-198.

Thanks for your help.
