Myard Post Base Plate for 6×6 Inches Wood Post
Size and compatibility: 5.3″ x 5.3″ x 1″; suitable for standard 6″ x 6″ posts (actual 5.5″ x 5.5″ in the market). Includes 2 pieces per pack. Best for homeowners installing multiple posts where uniform support is needed. The 1″ standoff aligns with building codes to keep wood elevated above concrete for drainage and longevity. The base features four “X” ribs for added strength and uses UV-stabilized nylon with glass fiber for durability.
Best-for reasoning: Best for projects requiring multiple, identical bases with reliable stability and weather resistance. The thicker sides and reinforced base provide robust support for outdoor posts, especially where long-term exposure is expected. Caution: verify post actual dimensions before purchase to ensure a perfect fit.

Size and kit: Includes 10 post bases, 100 stainless steel screws, and 10 concrete anchors. Center hole widened from 10mm to 20mm for easier alignment with J-bolts and screws. Anti-corrosion coating on galvanized steel provides long-term rust resistance. Best for larger installations like decks and pergolas where a complete hardware kit reduces extra shopping trips.
Best-for reasoning: Choose this for large projects or when you want an all-in-one kit to complete multiple posts without sourcing separate hardware. Limitation: bulk packaging may be unnecessary for small DIY jobs.

Buying Guide: Key Purchase Considerations
- Post compatibility: Most bases target nominal 6×6 posts with actual dimensions around 5.5″ x 5.5″. Verify post measurements before purchase.
- Standoff distance: A 1″ standoff is common and helps meet building code requirements for concrete or ground clearance.

- Included hardware: Some kits include screws, anchors, and bolts; others require separate purchases. Consider total project cost.
- Installation environment: Indoor/outdoor use, exposure to moisture, and wind loads influence base choice and durability.
- Adjustability: Bases with slot options or adjustable features provide flexibility for precise alignment on uneven slabs or during seasonal shifts.
