Patent pending, cap and base is held in place with pressure tabs that automatically and perfectly align the cap and base on the column shaft. There is no need for screws, nails or construction adhesive to hold the cap and base in place. Squaring the cap and base is much easier since there are no fasteners, you simply make any necessary adjustments after the cap and base is slid into pace. Once the cap and base are in position a good quality latex based caulking should be applied around the cap and base where they meet the column.
