A bridge top stop consists of a body typically comprising a pair of wings or plate members interconnected at their lower ends by a central web or coupling link of wedge-shaped cross section. One of the plate members has a pair of flanges along its lateral edges, which flanges cooperate with the wedge-shaped web to form a downwardly diverging, inverted Y-shaped guide channel through the bridge top stop body for reception of fastener elements therein. For mounting this bridge top stop in position on a pair of fastener stringers, the opposed inside edge portions of the stringers are manipulated into and through the inverted Y-shaped guide channel of the top stop body from its lower end, just as when a pair of such stringers is threaded through the similar guide channel of the usual slider for slide fastener assemblage. Some of the fastener elements including the topmost ones of the respective stringers will interengage within the top stop body. |
