Pelo que li de algumas definições e vi de imagens, é o mesmo que "strike plate".

A door strike is one of the primary components of a typical door locking system.
Most regular doors have three major parts that work together to keep the door secure.
The first two parts are the handle and the latch, both of which combined (along with several other smaller components) are commonly called the lockset. The handle is pretty self-explanatory; it’s the device that you grab and turn to open the door.
The latch is the small metal bolt that you will see sticking out of the side of the door when the door is open. Latches are typically spring-loaded, and they lock into place when the door is fully closed, keeping the door secure.
The third part is the door strike (also called the “strike plate”), which essentially looks like a metal plate with a hole (or holes) cut out of it. The door strike is fastened, usually by screws, onto the frame of a doorway, and it is carefully aligned with the lockset in order to give the latch a place to sink into when the door closes.
