The Simpson A21Z 2 in. x 1-1/2 in. x 1-3/8 in. ZMAX Galvanized Angle from Simpson Strong-Tie is a compact, reliable metal connector designed to reinforce 90 deg. connections across a wide range of light-duty and structural home repair and building projects. Built from 18-gauge steel and finished with a ZMAX zinc coating, this angle bracket helps produce joints that are stronger, straighter, and more consistent than angled nailing or screw fastening alone - making it a practical choice for both interior framing and exterior applications where moisture or treated wood is a concern.

Key Features

• Versatile connector for various 90 deg. connections and home repair projects - adapts to a broad range of building and repair tasks, reducing the need for multiple connector types on the job.
• Stronger than angled nailing or screw fastening alone - provides a more secure structural connection, giving you greater confidence in the integrity of each joint.
• Helps ensure joints are consistently straight and strong - acts as a reliable guide during installation, saving time and minimizing the frustration of misaligned corners.
• Made from 18-gauge steel - delivers durable, dependable performance for both light-duty repairs and applications requiring a solid structural connection.
• ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications - the enhanced zinc coating stands up to moisture and the chemicals present in treated lumber, making this angle well suited for outdoor and exposed installations.

Why This Product

• Built for outdoor and treated-wood conditions - the ZMAX zinc coating provides extra corrosion resistance beyond standard galvanized finishes, so this angle connector holds up in the demanding environments where many basic connectors fall short.
• A smarter alternative to fastening alone - by reinforcing 90 deg. joints with a rigid steel bracket, this connector creates a stronger and more consistent connection than relying solely on nails or screws, adding real structural value to any project.
• Versatile enough for a wide range of applications - from framing repairs to general construction joinery, this angle supports various connection needs, making it a useful addition to any toolkit rather than a single-use part.
