The Simpson HL73PC Black Powder-Coated Heavy L-Angle is a 3-gauge steel timber connector engineered to join timber members and reinforce right-angle connections while delivering a refined, decorative appearance suited to exposed wood applications. Part of Simpson's Decorative Hardware line, this pre-finished heavy angle brings together structural performance and an intentional aesthetic, making it a practical choice for timber framing, post-and-beam construction, and architectural carpentry where visible hardware is part of the design. Its clean, heavy-gauge profile promotes standardization and construction economy, and it is fully compatible with Simpson structural hardware.

Key Features

• Connects timber members and reinforces right-angle joints - purpose-built geometry keeps 90 deg. connections tight and stable under load, reducing the need for custom fabrication at critical joints.
• Resists uplift and diagonal forces in wood connections - the heavy 3-gauge steel construction handles the lateral and vertical stresses that commonly occur at timber framing and post-and-beam intersections.
• Black powder-coat finish - the pre-finished surface arrives ready to install in exposed applications, eliminating on-site painting and delivering a consistent, decorative look that complements visible wood framing.
• Installs with four 3/4-in. diameter bolts - a straightforward, bolt-only installation reduces hardware complexity and supports consistent, repeatable results across a project.
• Compatible with Simpson structural hardware - integrates directly into broader Simpson connector systems, supporting standardization across timber framing and ornamental structural applications.

Why This Product

• Structural performance meets decorative finish - unlike plain galvanized angles that must be hidden or painted on-site, this connector arrives pre-finished in black powder-coat, purpose-designed for exposed wood construction where the hardware is meant to be seen.
• Heavy-gauge steel for demanding timber connections - 3-gauge steel provides the thickness and rigidity needed to resist uplift and diagonal forces at right-angle timber joints, making this angle appropriate for structural applications, not just ornamental trim.
• Promotes job-site efficiency and standardization - the pre-finished, ready-to-install format and straightforward bolt-only installation help reduce finishing steps and keep timber framing and post-and-beam projects on schedule.
• Part of a coordinated decorative hardware system - as a member of Simpson's Decorative Hardware line, this heavy angle is designed to pair visually and structurally with other connectors in the series, giving architects and builders a cohesive look across exposed structural connections.
