Product Description
The Simpson Heavy Top-Flange Hanger for SCL 3-1/2 x 18-3/4 is a heavy-duty connector built for engineered lumber framing where high load transfer and connection integrity are non-negotiable. Designed specifically for structural composite lumber header applications, this top-flange hanger provides a reliable, code-friendly solution for beam-to-header connections in both residential and commercial construction. Its heavy-gauge steel construction and thoughtful fastener hole placement address the real-world demands of SCL installations, helping contractors and engineers achieve strong, lasting connections with confidence.
Key Features
- Heavy Top-Flange Design for SCL Headers - engineered specifically for structural composite lumber header connections, making it a natural fit for engineered lumber framing systems where precise load transfer is required
- 3-Gauge Steel Top Flange - delivers the heavy-load capacity needed for demanding beam-to-header applications, ensuring the connection holds up under the stresses of real structural loads
- 7-Gauge Steel Stirrup - provides a strong, rigid cradle for the supported member, maintaining alignment and bearing performance throughout the life of the connection
- Split-Prevention Fastener Hole Placement - holes are strategically positioned to reduce the risk of lamination splitting in the header, preserving the structural integrity of the engineered lumber
- Funnel Flange Installation Geometry - guides the beam into position during installation, reducing the time and effort required to seat the member correctly on the job site
- Simpson Strong-Tie Gray Paint Finish - provides a consistent, protected surface finish standard for interior structural applications, with a hot-dip galvanized option available for corrosion-sensitive environments
- Made in the United States - produced domestically, supporting quality assurance standards expected in professional structural hardware
Why This Product
- Purpose-Built for High-Load SCL Applications - unlike general-purpose joist hangers, this hanger is specifically engineered for structural composite lumber headers, meaning it is sized, gauged, and hole-patterned for the exact material and load demands it will face in the field
- Dual-Gauge Steel Construction Matches the Job - the combination of 3-gauge steel in the top flange and 7-gauge steel in the stirrup is not accidental - each component is sized to handle the stresses at its location, giving builders a hanger that is strong where it needs to be
- Lamination Protection Built Into the Design - the strategic fastener hole placement actively reduces the risk of splitting the SCL header during installation, protecting the investment in engineered lumber and avoiding costly on-site damage
- Flexible Finish Options for Different Environments - the standard gray paint finish suits most protected interior applications, while the available hot-dip galvanized finish extends the product's usefulness to corrosion-sensitive environments where moisture exposure is a concern

Frequently Asked Questions
What type of lumber is this hanger designed for?
The HGLTV3.56/18.75 is specifically engineered for structural composite lumber (SCL) header applications. It is designed to handle high load capacity requirements common in engineered lumber framing.
What gauge steel is used in this hanger, and why does it matter?
This hanger uses 3-gauge steel in the top flange and 7-gauge steel in the stirrup. This heavy-gauge combination delivers maximum structural performance, making it suitable for demanding, high-load header connections.
How does the Funnel Flange design benefit installation?
The Funnel Flange design allows for easy installation of beams by improving placement accuracy and reducing labor time. This feature simplifies the process of seating engineered lumber headers into the hanger during construction.
Is this hanger available in a corrosion-resistant finish for exterior or high-moisture applications?
Yes. While the standard version comes with a factory-applied Simpson Strong-Tie gray paint finish intended for interior applications, a hot-dip galvanized finish option is also available for applications requiring enhanced corrosion resistance.
