Need a multi point mortise lock for patio door
Best,

I can't confirm if the 82-265 will work based on these photos, unfortunately. Without the original to use as a reference, there is no way to confirm 100%. You will need to carefully review the dimensions we show on the 82-265 store page and use your best judgement if it will fit in the space provided.
I can at least tell you that the 82-265 is fully compatible with the 82-249 keeper. It might be a safe bet to get that just in case.
Nope, measurements are the only way. There won't be any stamp, code, sticker, or marking on your door that tells you what locking hardware it uses. Most doors like yours use generic parts, so the only way to find what you need is based on physical details and comparison.
