Lost locking mechanism

The latch on the slider wouldn't stay locked so tried to remove but it fell to the inside bottom of the frame. I need a replacement w/ instillation instruction. The slot for the lock is 3 inches w/ the screw holes 3.5 inches apart. Images attached should help identify what replacement part.

Take a look at our 82-218, this looks like it may fit. Also be sure to watch the video below.

Greetings-

I just received the replacement lock mechanism but it is slightly too long. Width & hole pattern look right. Because the orifice is an oval, that might be the problem. Seems off only about 1/8th inch. Do you have a replacement that would fit?

Thank you,
Frederick

The hole should be a little tight so that the mortise lock firmly installs. I'm afraid they do not make a version of the 82-218 with only that slight difference. I'm almost certain this is the correct lock. Watch the video above to see how we install it. It's a little tight there, too, but we are able to pop it in regardless.
