Product Description
The Simpson HL37 Heavy L-Shaped Angle is a heavy-duty right-angle connector from Simpson Strong-Tie, engineered to reinforce timber framing and structural wood joints where strength and long-term reliability are non-negotiable. Fabricated from 7-gauge steel with a G90 galvanized coating, this heavy angle resists uplift and diagonal forces while promoting standardization and construction economy across a wide range of structural applications. Whether you are a contractor building to code or an engineer specifying hardware for a demanding timber connection, the HL37 delivers the proven performance that construction professionals depend on.
Key Features
- Right-angle timber connection support - reinforces wood-to-wood joints and helps connect heavy timber members securely, reducing the risk of joint failure under load
- Uplift and diagonal force resistance - engineered to counter the forces that commonly compromise structural wood connections, adding stability to framing assemblies
- 7-gauge steel construction - provides the heavy-duty strength needed for demanding structural applications where lighter connectors are not sufficient
- G90 galvanized coating - delivers extra corrosion resistance, making the angle suitable for installation environments where moisture exposure is a concern
- Compatible with Simpson Strong-Tie structural hardware - integrates seamlessly with other connectors in the Simpson Strong-Tie system, supporting consistent, code-compliant installations
- Installs with 1/2 in. diameter bolts - uses standard bolt sizing to create a strong, secure connection between structural members without requiring specialized fasteners
Why This Product
- Trusted engineering behind every connector - Simpson Strong-Tie connectors are engineered and tested to perform and manufactured to the highest quality standards, giving contractors and engineers confidence that the hardware will hold up on the job
- Heavy-gauge steel for serious structural work - the 7-gauge steel build makes the HL37 well suited for heavy timber framing and other structural applications that demand a connector capable of handling substantial loads
- Corrosion-resistant finish for long-term durability - the G90 galvanized coating provides extra protection against corrosion, helping the connector maintain integrity over time in conditions where bare steel would deteriorate
- Promotes standardization and construction economy - the versatile design of this heavy angle supports consistent use across multiple connection points, simplifying procurement and installation on larger framing projects
