10-Piece Post Base Kit for 6x6 Timber

This kit contains ten zinc-plated carbon steel post bases designed for concrete pergola and patio installations. Each base features a 1.2 mm wall thickness and a 1 inch standoff that separates the timber from the concrete surface. The internal dimensions of 5.49 x 5.57 inch accept standard 5.5 x 5.5 inch and 5.5 x 6 inch wooden posts. The package weighs 10.58 lbs and includes all necessary mounting hardware.

Suits Deck and Pergola Builders.

These brackets are intended for contractors and DIYers anchoring 6x6 posts to existing concrete slabs or footings. The U-shaped positioning holes allow straightforward alignment during installation. Builders using posts wider than the 5.49 inch internal clearance will need a different bracket size. Projects requiring adjustable height or side-mounted connectors are not addressed by this fixed-standoff design.

Included Fasteners Cover Concrete and Timber Fixing

The bundle supplies ten M8*60 self-tapping screws, ten 12*60 expansion bolts, ten M8 washers and eighty M4*30 self-tapping screws alongside the ten base brackets. Expansion bolts secure each base into concrete while the M8 and M4 screws fasten the timber post into the bracket. No separate anchor or screw purchase is required for a standard ten-post installation.

Questions about this item

What size wooden post fits inside the 5.49 x 5.57 inch inner tube?

The bracket accepts 5.5 x 5.5 inch or 5.5 x 6 inch posts for a snug fit.

Will the 1 inch standoff clearance work with my existing concrete slab?

Yes, the 25.4 mm base-to-timber gap lifts the post above the slab to prevent moisture contact.

How can I confirm the post bases are level after bolting them down?

Use a spirit level across the 5.68 x 5.57 inch top plates; the U-shaped positioning holes allow fine adjustment before final tightening.
