The Simpson Strong-Tie HL55GPC Heavy Ornamental L-Shaped Angle with Gusset is a robust, architecturally refined connector engineered for right-angle structural connections where both performance and appearance matter. Part of Simpson Strong-Tie's Classic Collection, this heavy utility angle features modern smooth edges and clean, uncluttered lines - making it an exceptional choice for projects where connectors remain visible. Finished in a durable black powder coating, the HL55GPC delivers lasting corrosion resistance and a polished aesthetic suited to ornamental interior applications. Its 7-gauge steel construction and gusseted design provide superior strength, helping reinforce wood members at 90 deg. intersections while resisting uplift and lateral forces in demanding applications.

Key Features

• Ornamental Classic Collection Design: Smooth edges and clean lines make this connector ideal for visible installations where appearance is a priority.
• Black Powder-Coat Finish: Factory-applied black powder coating provides an attractive, durable surface that complements exposed architectural elements.
• Heavy L-Shaped Profile with Gusset: The gusseted L-shape adds structural rigidity, making it well-suited for demanding right-angle connections between two members.
• Resists Uplift and Lateral Forces: Engineered to resist both uplift and lateral forces, providing dependable performance in structural applications.
• Bidirectional Lateral Load Capacity: Achieves lateral loads in both directions when installed in pairs, offering versatility in connection design.
• 7-Gauge Steel Construction: Heavy-duty 7-gauge steel delivers the strength required for load-bearing ornamental and architectural applications.
• Made in the United States: Manufactured domestically, ensuring consistent quality and craftsmanship.

Frequently Asked Questions

Is this angle suitable for visible or exposed installations?

Yes. The HL55GPC is part of Simpson Strong-Tie's Classic Collection, which is specifically designed with smooth edges and clean, uncluttered lines for applications where the connector will remain visible. Its black powder-coat finish gives it a polished, architectural appearance well suited to ornamental interior installations.

What type of structural forces does the HL55GPC resist?

The HL55GPC is engineered to resist both uplift and lateral forces at right-angle connections. It also achieves lateral loads in both directions, making it a dependable choice for demanding structural applications where bidirectional performance is required.

What makes the gusseted design beneficial compared to a standard L-angle?

The gusset adds structural rigidity to the L-shaped profile, providing superior strength at 90 deg. intersections between two wood members. This makes the HL55GPC better suited for heavy-duty right-angle connections where a standard, non-gusseted angle may not offer sufficient reinforcement.

What is the connector made from and how is it finished?

The HL55GPC is constructed from 7-gauge steel and finished with a factory-applied black powder coating. The powder-coat finish provides durable corrosion resistance while delivering the attractive, consistent appearance expected of an ornamental connector.
