The Simpson HGLTV3.514 HGLTV Top-Flange Joist Hanger is a heavy-duty connector from Simpson Strong-Tie built specifically for structural composite lumber header applications that require high load capacity. Sized for an actual 3-1/2 in. x 14 in. engineered wood member, this top-flange hanger features strategically located nail holes that prevent header degradation by resisting splitting of laminations, and a Funnel Flange design that guides beams into place for faster, more reliable installation. Whether you are working with engineered lumber, I-joists, or weld-on structural assemblies, this hanger is engineered to deliver a secure, code-conscious connection.

Key Features

• Top flange constructed from 3-gauge steel - delivers the heavy structural strength needed to handle demanding high-load header applications without compromise.
• Stirrup constructed from 7-gauge steel - provides a rigid, durable cradle that keeps the joist or beam firmly seated and properly aligned.
• Strategically positioned top-flange nail holes - sized and located to prevent degradation of the header by resisting splitting of laminations, protecting the integrity of the structural composite lumber.
• Funnel Flange design - guides engineered beams into the hanger quickly and accurately, reducing installation time and minimizing the chance of misalignment.
• Compatible with weld-on applications - gives contractors and fabricators the flexibility to use this hanger in shop-fabricated or field-welded structural assemblies.
• Web stiffeners required with I-joists - ensures buyers plan for a complete, code-compliant connection when installing over engineered I-joist members.
• Simpson Strong-Tie gray paint finish - provides a consistent, professional appearance and a baseline level of surface protection for interior structural environments.

Why This Product

• Purpose-built for high-load SCL header connections - unlike general-purpose joist hangers, this hanger is designed specifically for structural composite lumber applications where elevated loads demand a more robust engineered solution.
• Dual-gauge steel construction optimizes both strength and formability - the heavier 3-gauge top flange anchors the hanger to the header with maximum holding power, while the 7-gauge stirrup provides the precise shaping needed to cradle a 3-1/2 in. x 14 in. engineered member securely.
• Lamination-protective nail placement reduces the risk of header damage - because the nail hole locations are engineered to avoid splitting laminations, the structural composite lumber header retains its full rated capacity throughout the life of the connection.
• Versatile enough for weld-on structural assemblies - the series' compatibility with weld-on applications makes it a practical choice for fabricators and contractors who need a single hanger solution that works across multiple installation methods.

Frequently Asked Questions

What size engineered lumber is this hanger designed to support?

This hanger is designed for an actual joist or beam size of 3-1/2 in. x 14 in., making it suitable for standard engineered lumber and structural composite lumber members of that dimension.

What fasteners are recommended for installing the HGLTV3.514?

Installation with (24) 0.162 in. x 3-1/2 in. Strong-Drive SCN Smooth-Shank Connector nails (Model: 16DHDG) is recommended for this hanger.

Are web stiffeners required when using this hanger with I-joists?

Yes. Web stiffeners are required with I-joists when using this hanger style to ensure a proper and code-compliant connection.

What gauge steel is used in the construction of the HGLTV3.514?

The top flange is constructed from heavy 3-gauge steel, while the stirrup is made from 7-gauge steel, providing the strength needed for high-load structural composite lumber header applications.
