The Simpson 3x7 Black Ornamental Heavy L-Shaped Angle with Gusset is a powder-coated structural connector from Simpson designed for right-angle connections where both strength and appearance are priorities. Its L-shaped profile and integrated gusset deliver robust reinforcement at 90 deg. junctions, resisting uplift and lateral forces, while the clean lines and black powder-coat finish make it a natural fit for exposed, architecturally visible installations. Part of Simpson's Classic Collection, this heavy utility angle bridges the gap between structural performance and decorative appeal.

Key Features

• Classic Collection Design with Smooth Edges - Modern, refined lines allow the connector to complement rather than detract from finished woodworking and architectural projects where hardware stays visible.
• Black Powder-Coat Finish - Provides durable protection against wear while delivering a consistent, attractive appearance suited to ornamental and interior exposed-connector applications.
• L-Shaped Profile with Integrated Gusset - The gusset adds substantial rigidity at the corner, reinforcing wood members at 90 deg. connections and improving resistance to uplift and lateral forces.
• Bidirectional Lateral Load Capability - When installed in pairs, connectors achieve lateral load resistance in both directions, expanding their usefulness in demanding structural scenarios.
• Made in the United States - Domestic production supports consistent manufacturing quality and material traceability for projects where sourcing standards matter.

Why This Product

• Form and function in one connector - Unlike purely utilitarian hardware, this heavy angle is specifically engineered for applications where the connector is exposed, combining structural reinforcement with an ornamental black finish that contributes to the finished look of a project rather than detracting from it.
• Purpose-built for demanding right-angle connections - The integrated gusset and heavy construction address real structural needs - resisting uplift and lateral forces at beam or member junctions - making this appropriate for both ornamental interior work and load-bearing applications.
• Flexible fastening options without load penalty - Lag screws of equal diameter (minimum 5 in. long) may be substituted for bolts in the beam with no reduction in load, giving installers practical flexibility on the job site.
• Scalable performance through paired installation - For projects requiring bidirectional lateral load performance, installing connectors in pairs unlocks the full structural capability of the design, making this angle adaptable to a wider range of connection demands.

Frequently Asked Questions

What type of finish does the HL37GPC have, and why does it matter?

The HL37GPC features a durable black powder-coat finish that protects against wear and corrosion while delivering a consistent, attractive appearance. This makes it especially well-suited for visible installations where the connector itself contributes to the finished look of a project.

What is the purpose of the integrated gusset on this angle bracket?

The integrated gusset reinforces the 90 deg. angle connection, significantly increasing load capacity over a standard angle bracket. It helps the connector resist both uplift and lateral forces where two wood members meet at a right angle.

Can the HL37GPC resist lateral loads in both directions?

Yes. When installed in pairs, the HL37GPC achieves lateral load resistance in both directions, providing balanced structural performance for demanding right-angle connections.

How heavy-gauge is the steel used in the HL37GPC, and where is it made?

The HL37GPC is built from 7-gauge steel for heavy-duty performance under significant load demands. Its Country of Origin is the United States.
