The Simpson Heavy Top-Flange Hanger for SCL 5-1/2 x 12-1/2 is a heavy-duty joist hanger built specifically for structural composite lumber header connections where high load performance and lamination integrity are non-negotiable. Purpose-built for engineered lumber framing systems, this top-flange hanger features a strategic hole pattern that prevents lamination splitting and a Funnel Flange design that simplifies beam seating during installation - making it a reliable choice for demanding residential and commercial framing applications.

Key Features

• Purpose-Built for SCL Headers - Engineered specifically for structural composite lumber applications, so the hanger performs correctly with the material properties and tolerances of engineered lumber rather than adapting a general-purpose product.
• Split-Prevention Hole Pattern - Fastener holes are strategically positioned to avoid splitting laminations, protecting the structural integrity of the header over the life of the assembly.
• Funnel Flange Design - Guides the beam into position during installation, reducing alignment effort on the job site and helping crews seat large engineered lumber members accurately and efficiently.
• Heavy-Duty Dual-Gauge Steel Construction - The top flange and stirrup are fabricated from different gauges of high-strength steel, providing a robust, load-capable connection suited to high-demand structural conditions.
• Simpson Strong-Tie Gray Paint Finish - Factory-applied finish provides baseline corrosion resistance for interior framing environments, with a hot-dip galvanized option available for projects requiring enhanced protection.
• Domestic Manufacturing - Produced in the United States, supporting consistent quality standards and reliable material sourcing for structural connectors used in code-compliant construction.

Why This Product

• Designed Around Engineered Lumber - Not Adapted to It - Unlike general-purpose hangers, this connector is purpose-built for SCL header connections, meaning the geometry, hole pattern, and load path are all optimized for the specific demands of structural composite lumber framing.
• Protects the Header Investment - The split-prevention hole pattern actively reduces the risk of lamination damage during fastening, helping preserve the full structural capacity of costly engineered lumber headers after installation.
• Speeds Up Beam Installation - The Funnel Flange design gives installers a built-in alignment guide when dropping large engineered members into place, cutting down on the adjustment time that commonly slows heavy framing work.
• Built for High-Load Commercial and Residential Use - Heavy-duty steel construction and approval for high-load beam-to-header connections make this hanger appropriate for projects where undersized or generic connectors would not meet structural design requirements.

Frequently Asked Questions

What type of lumber is the HGLTV5.50/12.5 designed for?

This hanger is engineered specifically for structural composite lumber (SCL) header applications that require high-load capacity. It is not a general-purpose hanger but rather a purpose-built solution for engineered lumber framing systems.

What gauges of steel are used in the construction of this hanger?

The top flange is fabricated from 3-gauge steel, while the stirrup is fabricated from 7-gauge steel, providing a heavy-duty, high-strength connection for demanding structural applications.

How does the hole pattern on this hanger prevent damage to the header?

The holes are strategically located to prevent splitting of the SCL laminations during fastening. This design protects the structural integrity of the header and prevents degradation over time.

Is a corrosion-resistant finish option available for this hanger?

Yes. The hanger comes standard with a Simpson Strong-Tie gray paint finish that provides baseline corrosion resistance for standard interior applications. A hot-dip galvanized finish is also available as an option for environments requiring enhanced corrosion resistance.
