Simpson Strong-Tie HL37HDG Heavy L-Shaped Angle - 3 x 7 Hot-Dip Galvanized

The Simpson Strong-Tie HL37HDG Heavy L-Shaped Angle is a robust, hot-dip galvanized steel connector engineered to reinforce right-angle connections between structural wood members. With its signature L-shaped profile and heavy-gauge construction, this multipurpose angle improves corner stability, promotes standardization across framing applications, and contributes to overall construction economy. Whether used in timber framing, post-and-beam construction, or general structural connections, the HL37HDG delivers dependable performance wherever two members meet at a 90 deg. angle.

Frequently Asked Questions

What are the dimensions of the HL37HDG Heavy L-Shaped Angle?

The HL37HDG has a Width-1 of 3-1/4 in., a Width-2 of 3-1/4 in., and a Length of 7-1/2 in., making it well-suited for reinforcing right-angle connections between structural wood members.

What type of corrosion protection does the HL37HDG have?

The HL37HDG features a hot-dip galvanized coating, which provides enhanced corrosion resistance compared to standard galvanized finishes, making it appropriate for demanding framing environments.

Can the HL37HDG resist forces in more than one direction?

Yes. When installed in pairs, the HL37HDG can achieve lateral load capacity in both directions, in addition to resisting uplift forces, making paired installation the recommended approach where multi-directional lateral loads are a concern.

What types of construction applications is the HL37HDG designed for?

The HL37HDG is designed for right-angle connections between two structural wood members, corner reinforcement in timber framing and post-and-beam construction, and applications requiring resistance to uplift and lateral forces.
