Anderson window circa 1993- thumb snapped off sliding door. Need replacement part. Does anyone know what part number I need?

Sure, check out our 82-043. The 82-043 is the newest version of the thumb latch you currently have and will be the closest thumb latch to what you currently have.

I think 82-241 looks closer. Please compare my pictures to that one and advise.

I see it only comes in gold and steel colored but the color doesn't make much difference as long as the lock fits. It's a back door leading onto the deck outside, and needs a very sturdy lock. The 82-043 looks very fragile. The old one is a very heavy metal -seems more sturdy than 043. The 82-241 looks like a stronger lock.

Also, the plate is rectangle more like the 82-241 not oval like the 82- 043.

You could possibly use the 82-241, yes, though I don't know if it's necessarily stronger. I only recommend the 82-043 because it is the newer version of the older style Andersen thumb latch that you appear to have. Keep in mind that the reason why these thumb locks usually break is because the internal mortise needs to be replaced, not through any fault of the latch itself. You may want to double check that just in case.

Does the new latch include the entire internal mortise? If not, what do I need to do to check it? Can a 67yr old senior female - who is usually pretty handy- do this or do I need a service (handyman) to fix this problem? LOL

Neither come with the inside mortise, but it could be our 82-037. This is the mortise lock most commonly used with the 82-043 and 82-241. You will have to remove yours and compare it to the specs we show online to be sure.

It is very easy! All you have to do is unscrew the thumb latch base that appears to still be installed, then the mortise lock itself.
