The Simpson Heavy L-Shaped Angle with Gusset HL79G is a heavy-duty structural connector from Simpson engineered to reinforce right-angle connections where two wood members meet at 90 deg. Its integrated gusset plate adds critical rigidity to the L-shaped profile, making this connector well suited for corner reinforcement, beam-to-post connections, and other demanding structural applications where both uplift and lateral forces must be reliably resisted.

Key Features

• L-shaped profile with integrated gusset - reinforces the joint beyond what a standard angle bracket provides, reducing flex and improving load transfer at the corner connection
• Heavy 3-gauge steel construction - delivers the material thickness needed for high-load structural connections, giving builders confidence in applications where lighter connectors would be insufficient
• Resists both uplift and lateral forces - addresses multiple load directions in a single connector, reducing the need for supplemental hardware at right-angle joints
• Achieves lateral loads in both directions when installed in pairs - allows bidirectional performance without additional brackets, simplifying the connection design
• Compatible with 3/4 in. diameter bolts or equivalent lag screws - lag screws of equal diameter (minimum 5 in. long) may be substituted for bolts in the beam with no reduction in load, giving installers flexibility in the field
• Made in the United States - domestic production supports consistent quality standards for structural hardware used in wood-frame construction

Why This Product

• Purpose-built for demanding right-angle connections - the combination of heavy-gauge steel and a gusset plate means this connector handles the kind of corner and beam junction loads that standard L-angles are not designed for
• Versatile fastening options with no load penalty - the ability to substitute lag screws for bolts in the beam without reducing rated load capacity gives contractors practical flexibility on the job site
• Scales to bidirectional load requirements - paired installation achieves lateral resistance in both directions, making this a single-product solution for complex structural connections rather than requiring multiple different connectors
• Backed by a recognized structural hardware brand - Simpson is a well-established name in structural connectors, and the HL79G is built to the same material and finish standards as the broader Simpson heavy-angle product line

Frequently Asked Questions

What are the dimensions of the HL79G angle connector?

The HL79G has a Width-1 of 7-1/4 in., a Width-2 of 7-1/4 in., and a Length of 9 in., making it a heavy-duty connector sized for substantial structural connections at 90 deg. angles.

What gauge steel is used in the HL79G, and why does it matter?

The HL79G is constructed from heavy 3-gauge steel, which is thicker and stronger than lighter-gauge connectors. This makes it well suited for high-load applications where resistance to uplift and lateral forces is critical.

How does the integrated gusset improve performance compared to a standard L-shaped angle?

The integrated gusset adds rigidity and corner stability beyond what a plain L-shaped profile provides. This extra reinforcement helps the connector better resist racking and deformation under load at right-angle connections.

Can the HL79G achieve lateral load resistance in both directions?

Yes. When the HL79G connectors are installed in pairs, the assembly achieves lateral loads in both directions, making paired installation the recommended approach for applications requiring bidirectional lateral resistance.
