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. |
