Simpson Strong Tie APB44 Post Base 4x4 Outdoor

Product Description

The SIMPSON STRONG TIE APB44 is a black steel post base engineered for 4x4 lumber applications in outdoor structural projects. It anchors vertical posts to concrete or other structural substrates, transferring vertical and lateral loads while keeping the post end elevated to reduce moisture contact. Licensed contractors, deck builders, and structural framers install this component as part of code-compliant framing assemblies. The base is designed to meet strict building code requirements for load-bearing outdoor connections, making it appropriate for projects where engineered performance and code compliance are required.

The APB44 is suited for residential and light commercial outdoor construction where 4x4 posts are used. Typical applications include decks, pergolas, carports, fencing, and similar above-grade wood frame structures. The black steel finish blends with common outdoor hardware aesthetics. Installation uses dedicated structural screws and hex head washers, which are sold separately and not included with this base.

Installation Notes

Installation should be performed by a qualified contractor familiar with applicable building codes, including the IBC and IRC fastener and connector requirements. Confirm anchor bolt placement and concrete cure before securing the base. Use only the manufacturer-specified structural screws and hardware for this connector — substituting standard wood screws will not meet engineered load ratings. Inspect the mounting surface for level and plumb before fastening the post.
