Buying Guide
What to consider when choosing 6 x 6 wooden posts and accessories:
- Material and finish: Cedar caps and untreated or treated posts influence weather resistance and appearance.
- Installation surface: concrete bases or wooden decks require different anchoring solutions.
- Fit and dimensions: confirm interior and exterior dimensions closely match your post size (5-5/8″ inner, 6″ outer is common).
- Durability and climate: pick coatings and materials suited to sun, rain, or snow exposure.
- Hardware compatibility: ensure bases, anchors, and caps are compatible with your post material (wood, composite) and with local building codes.
Practical tips for best results:
- Measure twice: ensure interior hub dimensions align with your 5.5″ x 5.5″ posts for a snug fit.

- Follow installation steps: use corrosion-resistant fasteners where required and verify level alignment for safety.
