The Simpson TA10Z-R 10-1/4 in. 12-Gauge ZMAX Galvanized Staircase Angle from Simpson is built for structurally sound staircase framing, delivering a cleaner, stronger connection without the compromises of conventional notching methods. Crafted from 12-gauge steel with a ZMAX zinc coating, this stringer connector stands up to exterior conditions and treated-wood applications where corrosion resistance is a priority. Beyond staircase use, it also serves as a reliable solution for heavy-duty 90 deg. connections where a narrow angle profile is required.

Key Features

• Eliminates complicated stringer notching - removes a labor-intensive step that can weaken stair stringers, resulting in a safer and more structurally consistent staircase frame
• 12-gauge steel construction - provides the rigidity and load capacity needed for heavy-duty framing connections, giving builders confidence in long-term joint integrity
• ZMAX galvanization - offers extra corrosion resistance specifically suited for exterior projects, high-moisture environments, and applications involving treated wood
• 10-1/4 in. length with narrow angle profile - fits tight framing situations where a standard wider angle would not clear surrounding structure, expanding where this connector can be used
• Versatile beyond stair framing - also ideal for heavy-duty 90 deg. connections where a narrow angle is needed, making it a practical addition to a wider range of structural framing tasks

Why This Product

• Stronger stairs without the sawwork - by eliminating the need for conventional stringer notching, this angle preserves the full depth of the stringer, maintaining structural integrity where it matters most in staircase construction
• Built for real outdoor conditions - the ZMAX zinc coating goes beyond standard galvanization to deliver extra corrosion resistance, making this connector a dependable choice for decks, exterior staircases, and treated-lumber applications
• A trusted name in structural connectors - Simpson engineering backs this angle bracket with design specifics tailored to staircase framing, so contractors and serious DIYers get a purpose-built solution rather than a generic bracket
• Dual-purpose versatility - its narrow profile and heavy-duty 12-gauge construction make it equally useful for tight 90 deg. framing connections beyond stair stringers, reducing the number of different connectors a builder needs on a job
