Simpson Strong-tie RTU2 Rigid Tie Connector 2x Members

Product Description

The SIMPSON STRONG-TIE RTU2 is an 18-gauge galvanized steel rigid tie connector designed to join two 2x wood members crossing at a 90-degree angle. It provides a mechanical connection at the intersection point, transferring load and resisting racking forces across the joint. Licensed contractors, framers, and structural repair professionals install this hardware wherever intersecting lumber members require a positive mechanical tie. The galvanized steel construction resists corrosion in standard interior framing applications. Installation requires two SD8 x 1.25 screws into the post member and four SD8 x 1.25 screws into the joist member for a total of six fasteners per connector.

The RTU2 is suited for residential framing, lattice construction, and structural repair work where two 2x lumber members cross at a right angle and require reinforcement. It is commonly used in deck substructure repairs, partition framing tie-ins, and lattice panel framing where rigid intersections are required. Home repair applications involving cross-member reinforcement are also a typical use case for this connector. Each connector is sold individually and is sized specifically for standard dimensional 2x lumber.

Key Features

• Connects two 2x lumber members crossing at a 90-degree angle
• 18-gauge galvanized steel construction for corrosion resistance
• Positive mechanical connection resists racking and separation at intersections
• Fastens with six SD8 x 1.25 screws total — two in post, four in joist
• Suitable for lattice construction, framing tie-ins, and structural repair

Compatibility

Designed for use with standard dimensional 2x lumber members intersecting at 90 degrees. Requires SD8 x 1.25 screws for proper installation per manufacturer guidance.

Installation Notes

Installation is performed by qualified framers, carpenters, or general contractors following applicable building codes. Before installing in a load-bearing application, confirm that the connector placement and fastener schedule meet local structural requirements. Use only the specified SD8 x 1.25 screws — substituting fastener type or size may compromise the rated connection. Position the connector squarely over the intersection before driving fasteners to ensure full bearing on both members.
