ABSTRACT:
A mullion latch is provided that will firmly secure a mullion post and yet permit the mullion post to be readily removable and reinstallable without tools. The mullion latch is used in conjunction with a double door opening that is designed to accommodate two single doors making use of the mullion post for their locking mechanisms, such as panic rim devices. Adapters are provided which may be used with the mullion latch in combination with a variety of mullion shapes, extruded or otherwise, that are employed in double door mullion assemblies, thereby negating any need to replace existing mullion posts when being adapted to employ the mullion latch. An assembly kit is provided for retrofitting or adapting existing mullion posts to be readily removable and reinstallable which includes the mullion latch combined with an adapter for use with a variety of existing moveable hollow core mullion shapes.
