Post base kit for 3.5 inch columns

The VEVOR QBLZ-4in-10 kit supplies ten powder-coated carbon steel post bases. Each bracket measures 3.8 by 5.5 by 6.4 inches with an inner size of 3.6 by 3.6 inches. The 2 mm wall thickness and full-wrap design secure 3.5 inch timber posts for deck, railing or pavilion structures.

Suits deck builds needing ten identical anchors

Builders installing multiple posts on a single project gain a consistent hardware set with 90 Phillips screws, 44 self-tapping screws, 44 serrated sockets and one thin wrench included. Projects requiring adjustable height, angled mounting or a different post cross-section will need alternative connectors.

Carbon steel resists deformation under constant load

The 0.08 inch thick material and spray coating maintain structural integrity and corrosion protection during prolonged outdoor exposure. The wrapped geometry distributes weight evenly around the post, limiting wobble when the assembly carries permanent roof or deck loads.

Questions about this item

Do I need to supply my own 3.5 x 3.5 inch wood posts for these 3.6" inner brackets?

Yes, each bracket is sized for a 3.5x3.5 inch column and the kit contains only the metal bases and fasteners.

Will the included 90 Phillips screws and 44 self-tapping screws work with my existing pressure-treated lumber?

The kit provides 90 Phillips screws and 44 self-tapping screws designed for wood installation; pilot holes are recommended for dense treated lumber.

How can I confirm the 10 post bases are seated correctly after bolting them down?

Check that each 3.8x5.5x6.4 inch base sits flush on the footing, the 3.6" inner pocket fully wraps the 3.5" post, and all 90 Phillips plus 44 self-tapping screws are tight with no wobble.
