Simpson HL33HDG Heavy L-Angle is a heavy-duty right-angle connector from Simpson, engineered to connect timber members and reinforce structural right-angle joints in both interior and exterior framing applications. Formed from 7-gauge steel with a hot-dip galvanized finish, this heavy angle delivers the load resistance and corrosion protection that engineers and contractors depend on for demanding wood-framing projects. Its versatile design promotes standardization and construction economy, and it is compatible with Simpson structural hardware for seamless integration into broader framing systems.

Key Features

• Connects timber and reinforces right-angle joints - provides a reliable mechanical connection where two members meet at a 90 deg. angle, reducing reliance on fasteners alone and improving overall joint integrity.
• Resists uplift and diagonal forces in wood connections - engineered to handle the lateral and vertical loads common in structural framing, helping keep assemblies secure under real-world stress.
• Made from 7-gauge steel - the heavy-gauge construction delivers the strength and rigidity needed for load-bearing timber connections without adding unnecessary bulk.
• Hot-dip galvanized finish - the HDG coating offers extra corrosion resistance compared to standard finishes, making this connector well suited for exterior installations and applications involving treated wood where moisture and chemical exposure are concerns.
• Compatible with Simpson structural hardware - integrates directly into framing systems built with genuine Simpson connectors, supporting a consistent, code-compliant approach across the entire project.

Why This Product

• Built for exterior and treated-wood use - hot-dip galvanization provides a level of corrosion resistance that standard coatings cannot match, making this angle a practical long-term choice for decks, exposed framing, and pressure-treated lumber applications.
• Heavy-gauge strength where it matters most - 7-gauge steel construction means this connector handles the uplift, shear, and diagonal forces that lightweight angles simply are not rated to address, giving builders confidence in critical connection points.
• Engineered and tested to perform - Simpson connectors are manufactured to rigorous quality standards and are the trusted choice of engineers and contractors, making this angle a proven option whether the project is a home improvement job or a code-compliant structure.
• Promotes construction economy and standardization - the versatile heavy angle design reduces the need to source multiple specialty brackets, streamlining procurement and installation across timber framing projects of varying scale.

Frequently Asked Questions

What type of connections is the HL33HDG designed for?

The HL33HDG is designed to connect timber and reinforce right-angle connections, making it ideal for applications where two members meet at a 90-degree angle. It also resists uplift and diagonal forces in wood connections.

What hardware should be used to install the HL33HDG?

The HL33HDG should be installed with 1/2 in. diameter bolts.

Why is hot-dip galvanization important for this angle connector?

Hot-dip galvanization (HDG) offers extra corrosion resistance, making the HL33HDG well suited for exterior and treated-wood applications where standard coatings may not provide adequate protection.

Is the HL33HDG compatible with other Simpson Strong-Tie products?

Yes, the HL33HDG is compatible with Simpson Strong-Tie structural hardware, allowing it to integrate seamlessly into broader framing and structural systems that use genuine Simpson Strong-Tie connectors.
