A mullion for a door assembly, the mullion comprising:
- a core having a first side wall and a second side wall opposite the first side wall, the first side wall defining a first linear plane and the second side wall defining a second linear plane;
- a first pair of recess points including a first stop recess and a first rabbet recess, each of the first stop recess and the first rabbet recess extending into the core from the first side wall;
- a second pair of recess points including a second stop recess and a second rabbet recess, each of second stop recess and the second rabbet recess extending into the core from the second side wall;
- a top piece having a stop portion and a rabbet portion;
- a first extension and a second extension projecting from the stop portion that each align with and project into a respective one of the first stop recess and the second stop recess to secure the stop portion onto the core;
- and
- a third extension and a fourth extension projecting from the rabbet portion that each align with and project into a respective one of the first rabbet recess and the second rabbet recess to secure the rabbet portion onto the core.
A door mullion comprising:
- a core including a core stop end, a core rabbet end, a first core side wall, and a second core side wall;
