Details

Build your project on strength and style with the Avant Post Base by Simpson Strong-Tie. Simpson post bases are the ideal foundation choice for outdoor projects like pergolas, pavilions, patio covers and more to keep your column bases and wood posts secure and strong.

Crafted from ZMAX® galvanized steel, the Avant adjustable post base is corrosion-resistant and features a rich, black powder-coated finish. With a one-inch rise from the ground surface, this Simpson Strong-Tie base will protect your wood post bases and column ends from rotting by preventing contact with groundwater and moisture.

Simpson post and column bases are perfect for wood to concrete connections, among others. The Avant base anchors a wood post or support column to a concrete, brick or wood surface with reliable strength.

To complete installation of the Avant Side Plates to the Simpson Strong-Tie Base you'll need additional hardware. The Structural Wood Screws and Hex Head Washers will secure the plates and give the finished look of fortified pergola.
