There's no such trap.  There is a low-memory global called MBarHeight.
Like all system low-memory globals, you should avoid writing to it;
Inside Mac v5 allows it to be written only by menu bar definition
procedures, and only to be set to a value larger than the size of the
system font.

Despite the fact that it's so commonly done, overwriting the menu bar
is a violation of the Mac user interface guidelines and should be
avoided.
