The Simpson TJC57 5-1/8 in. x 7 in. Galvanized Jack Truss Connector is a field-adjustable structural connector built by Simpson Strong-Tie for jack truss applications where angle flexibility and installation efficiency matter. Engineered and tested to meet the performance demands of both residential and commercial framing, this connector gives builders a reliable solution for connecting jack trusses at a wide range of roof pitches and configurations - without the need for a bevel cut.

Key Features

• Versatile jack truss connector design - purpose-built for jack truss connections, making it a dependable fit for a variety of framing layouts and roof configurations
• Adjustable from 0 deg. to 85 deg., shipped at 67.5 deg. - arrives pre-bent at a commonly used angle while remaining fully adjustable on the job site, reducing the need for additional hardware across different pitch scenarios
• Nail hole locations allow for easy installation - pre-punched holes guide fastener placement accurately, helping speed up installation and reduce guesswork
• Made from 16-gauge steel - heavy-gauge construction delivers the structural strength required for load-bearing truss connections
• Zinc Galvanized (G90) coating - provides extra corrosion resistance, helping the connector maintain long-term integrity in demanding or moisture-prone environments
• Engineer trusted and contractor proven - backed by Simpson Strong-Tie's rigorous engineering and testing standards, giving builders confidence that the connector will perform to specification
