Simpson Strong Tie U44 4x4 Joist Hanger

Product Description

The SIMPSON STRONG TIE U44 is a 4x4 joist hanger designed to secure joists to headers in wood-frame construction. Built from 16-gauge galvanized steel, it resists corrosion and delivers the load-bearing strength required for structural framing applications. The U44 features speed prongs that hold the hanger in position during nail-off, reducing layout time on the job. Fastening requires four 10D or 16D nails driven into the header and two 10D x 1.5-inch nails driven into the joist face. This hanger is installed by framers, carpenters, and general contractors working on decks, floor systems, and roof structures.

The U44 is suited for both residential and light commercial framing projects where 4x4 lumber members are attached to a structural header or beam. Typical applications include deck framing, floor joist systems, and pergola or covered patio construction. The galvanized coating makes it appropriate for treated-lumber contact in exterior and semi-exposed conditions. Each package contains 50 hangers, making it practical for production framing where multiple bays require consistent connector placement.

Installation Notes

Installation is performed by licensed carpenters or framers in accordance with local building codes and applicable provisions of the International Building Code.
