I am looking for the proper English name of the little hole in door frames where the latch goes in. Specifically, I want to know what that hole is called for "indoor" doors, without a lock, e.g. the door to a bedroom. Please note that I want to refer to the hole itself, not to the metal plate surrounding it.

Is there a term in common use, as opposed to a professional term? For example, "I got my finger stuck in the ....". Even if there's not one word to describe it, how would a native English speaker finish that sentence?

Here's a picture of what I'm talking about:

door frame hole


The hole itself is a mortise which is:

a hole or recess cut into a part, designed to receive a corresponding projection (a tenon) on another part so as to join or lock the parts together.

Example: The picture shows the strikeplate installed over the mortise.

More commonly though, strikeplate hole would likely be more widely understood.


I'll gladly yield to any professional carpenters. But to the best of my knowledge, the only name for this is "the hole in the strike plate".

The hole on the other side, that is, the hole in the door that the bolt slides through, is called the "edge bore". But I don't know of any corresponding term for the hole in the door frame.

(But if you look at the last door that I installed, you will quickly see that I am not a professional carpenter. :-)


I found a term on another website that referred to a "box", and I think that is what the doorframe hole may be called.
