  • Patent number: 9314069
    Abstract: A top stop made of a flexible material and that cooperates with at least a portion of a slider body. The top stop includes a body having a fin that extends upwardly from the body and that includes a contour that generally conforms to a leading edge of the slider body. In some versions, the top stop has two extensions that project from the body and that form a gap that is configured to snugly receive a connecting neck of the slider body in such a way that water is prevented from penetrating the slider body.
