Abstract
An improved astragal assembly for double door entryways includes an extruded aluminum frame into which upper and lower flush bolt assemblies are slidably disposed. The flush bolt assemblies include a relatively long metal bolt about which is injection overmolded a series of retainer guides, which ride in the frame. Locking mechanisms are also integrally overmolded onto the bolts. The frame and all components of the astragal assembly are symmetrical and reversible so that the assembly is non-handed; that is, it can be adapted to both a right hand swing and a left-hand swing inactive door. A unique strike plate mounting system and bottom-sealing block are provided and the upper end of the assembly includes means for sealing against the stop of a head jamb. Drafts at the upper and lower inside corners of the doors of a double door entryway are thus prevented.
