Simpson Strong Tie APB66R Post Base 6x6 Black Galvanized

Product Description

The SIMPSON STRONG TIE APB66R is a black rough galvanized steel post base designed to anchor 6x6 rough-cut lumber posts to concrete or structural foundations. It provides a rigid, code-compliant connection that resists uplift, lateral movement, and shear forces common in high-wind and seismic zones. The hot-dip galvanized finish with black coating offers corrosion resistance suited to outdoor and exposed environments. This hardware is typically installed by carpenters, deck contractors, structural framers, and general contractors working under local building codes that require engineered connectors for load-bearing post connections.

The APB66R is engineered for use in deck construction, fence framing, pergola builds, carport structures, and any outdoor application requiring a positive post-to-foundation connection. It is sized specifically for 6x6 rough lumber, which runs slightly larger than dimensional lumber, making it a correct fit where rough-sawn or full-dimension timbers are specified. It is suited for both residential and light commercial applications in regions with seismic or high-wind code requirements. Compatible Outdoor Accents structural screws and hex head washers are sold separately and may be used to complete the installation.

Compatibility

Designed for use with 6x6 rough-cut dimensional lumber posts in deck, fence, pergola, and structural framing applications requiring seismic or high-wind rated post base connections.

Installation Notes

Installation should be performed by a qualified carpenter or contractor in accordance with local building codes, including applicable sections of the IBC or IRC governing structural connectors and post base anchorage. Power down any adjacent electrical systems and ensure concrete anchor points have fully cured before setting the base. Use only fasteners specified or approved for this connector type — do not substitute with non-rated hardware. Verify post base orientation and alignment before final fastener installation, as repositioning after anchoring may compromise the connection.
