OZCO’s Ornamental Wood Ties (OWT) Ironwood Post Base Kits are more than just functional—they’re designed to elevate the aesthetics of any outdoor post structure. Whether you're building a pergola, railing, arbor, or mailbox, these post bases offer both durability and architectural flair. The visible hardware adds character and negates the need for concealment, saving both time and materials. All hardware is approved for use with ACQ-treated lumber.
Built from heavy-gauge steel, each base is hot-dip galvanized after fabrication and then finished with an exterior-grade black powder coat—offering superior resistance to rust and corrosion, even in harsh outdoor conditions. Compatible with a variety of surfaces, including wood, stone, concrete, and OZ‑POSTs, these bases elevate your posts off the ground to reduce moisture exposure.
Each base kit includes:
- 1 Post Base
- 4 Decorative Plates
- 8 Hex Cap Nuts
