Abstract
A wear member for earth working equipment and a wear assembly including a plurality of such wear members. The wear member defines a longitudinal axis and comprises: a body defining a rearward opening cavity dimensioned to receive a base; first and second lateral portions extending from opposing sides of the body and defining a front edge for engaging earth. The first lateral portion defines a complementary formation to the second lateral formation to enable axial insertion and removal of a wear member mounted between adjacent wear members due to the open removal path defined by the complementary formations. The complementary formations also resist rotational movement of the wear member about the longitudinal axis.
