The Simpson HL55PC Heavy L-Shaped Angle is a pre-finished structural connector from Simpson's Decorative Hardware line, purpose-built to connect timber members and reinforce right-angle connections in exposed wood construction. Fabricated from 7-gauge steel with a black powder-coat finish, this heavy angle delivers genuine structural performance while contributing a clean, intentional appearance to any project where hardware stays visible - making it equally at home on a timber frame porch, pergola, or interior post-and-beam assembly.

Key Features

• Connects timber members and reinforces right-angle joints - designed specifically for heavy timber applications where a secure, load-bearing 90 deg. connection is required
• Resists uplift and diagonal forces in wood connections - adds structural integrity at joints that experience lateral and vertical stress, improving overall stability
• Made from 7-gauge steel - the heavy-gauge construction provides the rigidity and strength needed for demanding timber framing applications
• Black powder-coat finish - the pre-finished surface delivers a polished decorative look suited for exposed applications, eliminating the need for field finishing
• Compatible with Simpson Strong-Tie structural hardware - integrates seamlessly into broader connector systems, supporting standardization and construction economy across a project

Why This Product

• Structural performance meets decorative intent - unlike plain utility connectors, this angle is engineered to handle heavy timber loads while looking finished and intentional in any exposed application
• Pre-finished in the shop, ready for the field - the black powder-coat arrives fully applied, saving time on projects where visible hardware must complement the final aesthetic without additional prep work
• Built for standardization and construction economy - as part of the HL series, this angle helps crews establish consistent, repeatable right-angle connections across timber framing projects, reducing layout time and material waste
• American-made heavy-gauge construction - the 7-gauge steel body is produced in the United States, reflecting the material consistency and quality control that structural timber connections demand
