Tilt Latch Replacement

Thanks for posting, and good work narrowing it down to these two tilt latches--I agree that they are your best bet. The difference between the 26-243 and 26-244 versus the 26-419 and 26-420 is the size of the 'locking tab' on the underside of the latch body. See the diagrams below. The 26-243 has a locking tab that is 3/16", whereas the 26-419 measures at 3/8". Assuming all other dimensions check out, whichever choice best matches your tilt latch is what you should go with. Let us know if you have any questions.

Thanks for the kind words! Let us know if you need anything else. 

It's not really smaller, no. I actually posted dimensions for both parts above that you can review above. They are identical aside from the position of the locking "tooth" underneath. 

Can you tell me exactly how your part differs? In what aspect is it too big? Referring to those measurements I shared above, which one is different? Can you also tell me precisely how?
