Buying Guide
Key purchase considerations when selecting a 6×6 rough cut post base:
- Post compatibility: Confirm nominal vs actual post dimensions and whether the base accommodates rough-cut 6×6 timber.
- Material and finish: Choose galvanized steel or powder-coated finishes for weather resistance and long-term durability.
- Standoff and drainage: A raised base helps water drain away from the post, reducing rot risk; consider 1-inch or more standoff where applicable.
- Hardware inclusion: Some kits include all necessary screws and nuts; if not, budget for compatible fasteners.
- Code requirements: In regions with seismic or high-wind design criteria, select bases that meet or exceed local code expectations.
- Ease of installation: Snap-together or two-piece designs save time; verify if fasteners are needed for your project.
- Aesthetics: Decorative plates or skirt options can produce a cleaner look on visible posts.
