The 6" x 6" x 8ft column un-primed MDF shaft is shipped with 4-- 8 ft sides, unassembled so that it can be used to wrap a jack post, lolly post or an existing support. The shaft is made up of four sides that go together using lock miter joints for easy assembly. We provide installation instructions, water-proof PVC installation cleats, screws, mounting hardware, glue, tape and the material pre-cut for the base and cap to be installed on site.
