Tribeca Latch

Question

My latch broke -- the internal part that secures the locking mechanism.  From what I saw in the video, I only need the latch part.  However, the description says "Keep in mind that the reason why these thumb locks normally break is because the internal mortise needs to be replaced as well, not through any fault of the thumb latch itself."    Can you explain further? Not sure what the mortise is.  Don't want to order an item I don't need - but don't want to NOT have all the parts I DO need.  See photo  Half the turning mechanism broke - believe I only need latch assembly.  Thanks in advance for your help.

The mortise is the internal mechanism that the latch interacts with. When you turn the lever, a hook protrudes from the door; that hook is part of the mortise. You need to make sure your mortise is in working condition before you buy anything to be 100% sure. This is easily done by using a screwdriver to throw it manually. If the hook comes out okay, then there's no issue. If it hangs up, though, then you have a problem.

Your mortise is very likely a match for our 82-037.
