ABSTRACT:
Central to the invention is a universal, center case sub-assembly from which, by adding components thereto, one may fabricate a rim style center case assembly, or a concealed-vertical style center case assembly, or a surface-vertical style center case assembly, or a combination rim and vertical style center case assembly, for a panic-type exit device. Besides minimizing the number of diverse components and parts required for the fabrication of the aforesaid center case assembly styles, the universal sub-assembly comprises an improved design which offers a marked mechanical/leverage advantage to the trim linkage.
