The Simpson HL33 Heavy L-Shaped Angle is a structural connector built to reinforce right-angle joints in timber framing and wood construction. Formed from heavy-duty 7-gauge steel and finished with a G90 zinc galvanized coating, this heavy angle delivers the durability and corrosion resistance that engineers and contractors rely on for demanding structural work. Its versatile L-shaped profile promotes standardization and construction economy, and it is fully compatible with Simpson Strong-Tie structural hardware, making it a practical choice whether you are framing a residential structure or building to strict code requirements.

Key Features

• Reinforces right-angle timber connections - the L-shaped profile securely ties wood members at 90 deg. joints, adding strength where framing corners are most vulnerable
• Resists uplift and diagonal forces - engineered to handle the lateral and vertical loads that commonly stress wood-to-wood corner connections in structural framing
• Made from 7-gauge steel - heavy-gauge construction provides the rigidity and load capacity needed for demanding timber framing applications
• G90 zinc galvanized finish - the G90 coating delivers extra corrosion resistance, helping the connector hold up in moisture-exposed and weather-prone environments
• Compatible with Simpson Strong-Tie structural hardware - integrates with other connectors and fasteners across a project, supporting a consistent, code-compliant system
• Installed with 1/2 in. diameter bolts - bolt-based fastening creates a solid, reliable connection suited to heavy timber framing demands

Why This Product

• Engineered and tested for structural performance - Simpson Strong-Tie connectors are manufactured to high quality standards and engineered to perform, giving builders confidence on projects where code compliance and structural integrity are non-negotiable
• Heavy-gauge steel for serious structural work - at 7-gauge, this heavy angle is built for applications where a lighter connector simply would not provide adequate strength at load-bearing timber joints
• Corrosion-resistant finish extends service life - the G90 galvanized coating adds a meaningful layer of protection against rust and degradation, making this connector a dependable long-term choice in challenging conditions
• Promotes standardization across framing projects - the versatile design works wherever two wood members meet at a right angle, helping crews streamline installations and reduce the need for custom solutions on the job site
