The Scaffoldmart safety mid-post is for use when the length of a tower is more than 7' or longer than one set. The safety mid-post accepts the 7' single safety rail, and has a galvanized adjustable u-shaped toe board acceptor. We sell a 7' toe board that works in conjunction, or simply cut a piece of 1" x 6" wood toe board and drill a quick hole for a bolt or nail to lock into place. The purpose of the toe board is to prevent items from being kicked or knocked off and hurting someone. The body of the scaffold safety mid-post is powder coated yellow.
