Product Description
The Simpson Double 3-1/2 x 20 Heavy Top-Flange Hanger for SCL is a heavy-duty engineered connector built for high-load structural composite lumber header connections. Designed by Simpson to pair with double 3-1/2 x 20 engineered lumber beam profiles, this top-flange hanger delivers dependable load transfer in demanding residential and commercial framing assemblies where standard hangers fall short.
Key Features
- Heavy-duty double top-flange configuration - supports paired 3-1/2 x 20 engineered lumber headers, providing the load capacity needed for critical structural connections that single hangers cannot match.
- Top-flange mounting design - allows the hanger to bear directly on the carrying member, streamlining installation and reducing the number of steps required to complete a secure connection on the jobsite.
- Precision-located fastener holes - positioned to prevent lamination splitting in engineered lumber, protecting the structural integrity of SCL headers and reducing the risk of costly callbacks.
- Heavy-gauge steel construction - the top flange is formed from 3 Ga. steel and the stirrup from 7 Ga. steel, delivering the rigidity and durability that high-load framing applications demand.
- Simpson Strong-Tie gray paint finish - provides a consistent, protected surface suitable for standard interior framing environments, with a hot-dip galvanized option available for projects requiring greater environmental resistance.
- SCL-specific engineering - purpose-built for structural composite lumber header applications, ensuring compatibility with the material properties and load characteristics of engineered lumber assemblies.
Why This Product
- Built for engineered lumber demands - unlike general-purpose joist hangers, this connector is specifically engineered for SCL header applications, meaning the fastener placement and gauge selection are calibrated to the unique performance requirements of engineered lumber framing.
- Trusted Simpson quality, domestic production - produced in the United States under Simpson quality standards, this hanger gives builders and engineers confidence in consistency and traceability for commercial and residential projects alike.
- Double configuration reduces connection points - by handling both members of a double 3-1/2 x 20 assembly in a single hanger, it simplifies the framing process and keeps structural connections clean and code-consistent.
- Finish flexibility for varied project conditions - the standard gray paint finish covers typical interior applications, while the availability of a hot-dip galvanized finish means this hanger can be specified for projects where environmental exposure is a concern.

Frequently Asked Questions
What type of lumber is the HGLTV420-2 designed to support?
The HGLTV420-2 is specifically engineered for structural composite lumber (SCL) header applications. It is designed to handle the high-load demands of engineered lumber assemblies, making it suitable for critical structural connections where standard hangers may not provide adequate capacity.
What beam size does this hanger accommodate?
This hanger is configured to accommodate a 3-1/2 x 20 beam profile. Its double configuration is designed to provide paired support for engineered lumber assemblies of that specific size.
What materials and gauges are used in the construction of this hanger?
The HGLTV420-2 features a heavy-duty construction combining a 3-gauge steel top flange with a 7-gauge steel stirrup. The hanger is finished with a factory-applied Simpson Strong-Tie gray paint coating, which provides protection suited for standard interior and protected structural environments.
How does the fastener hole placement help protect engineered lumber headers?
The fastener holes are precisely located to prevent splitting of laminations within the engineered lumber header. This split-prevention hole placement preserves the structural strength of the header by avoiding fastener placement in areas that could cause degradation or separation of the laminated material.
