Abstract: A slat for use in chain link fences is provided. The slat generally includes an elongated, imperforate body member and first and second fins extending from the body member to provide privacy and to lock the slat within a channel of a chain link fence. The first and second fins include end legs which are configured and oriented to extend proximally and distally, respectively, relative to the body member toward fins of adjacently positioned slats to provide privacy. Further, the first and second fins are configured and oriented to extend into knuckles of a chain link fence, to wedge into the knuckles to secure the slats within the channels of the chain link fence. The fins may also include strands on the end legs which are capable of wrapping about the knuckles to lock the slats within the channels.
