DEFINITION

Classification: 24/578

Including complementary shaped and alternately useable interlocking faces:

(under subclass 575) Dissociable mating member wherein each mating member includes two distinct interlocking faces having configurations which are structural counterparts of one another and which are each only capable of being alternately used with the opposed mating member to engage and interlock with their counterpart configuration thereon.

(1) Note. A mating member having two distinct complementary interlocking faces alternately usable before its mounting to a supporting surface, but which is intended to utilize only one of these faces after its mounting is proper for this subclass.
