Notch Standards

"Notch" is the common denomination of the normally small openings in corners ("corner notches") and along edges ("edge notches") of plates. In other contexts they may be called "scallops" or "rat holes". Notches (only edge notches) may also be set along traces of profiles but must not in this case be part of the end cut of the profile.

Some corner notches are supposed to be used only in brackets.
