Abstract
Abstract An end channel member for office space dividing panels is provided. In section, the channel member includes a portion containing a vertical array of slots for receiving a bracket hook. The slotted portion is contained at the base of a recess with the surfaces defining the sides of the recess serving to capture the bracket hook and thereby prevent it from swaying from side-to-side. The longitudinal ends of the channel include post clips at least one of which is free to float to some extend so as to facilitate installation.
