Product Description
The Simpson MIT314 Top-Flange Joist Hanger for 2-1/2 in. x 14 in. Engineered Wood from Simpson is engineered to support standard 90 deg. connections of I-joists to headers, delivering maximum down loads while requiring a minimum number of fasteners. Designed to be installed before the joist is placed, this top-flange hanger features a Funnel Flange design for easier member placement and positive-angle nailing (PAN) specifically created for I-joists - making it an efficient, cost-effective alternative to welded hangers in engineered wood framing applications.
Key Features
- Positive-angle nailing (PAN) - minimizes splitting of the I-joist flanges while allowing nailing from a more accessible angle, saving time on the job without compromising structural integrity
- Nail hole material is not removed with PAN - preserves the strength of the connection at the nail point, maintaining full load performance
- Funnel Flange design - guides the joist into position more easily during installation, reducing placement time and improving accuracy before fastening
- Optional triangle nail holes for increased uplift capacity - gives installers flexibility to meet higher uplift demands when used with properly-secured web stiffeners
- Optional fastening with PAT for steel applications - allows the hanger to work with steel headers, broadening its compatibility across different framing assemblies
- Made from 16-gauge steel with a Zinc Galvanized G90 finish - provides the structural rigidity and corrosion resistance required for long-term performance in demanding framing environments
- Cost-effective solution for standard 90 deg. connections - delivers reliable engineered wood joist support at a lower cost compared to welded hanger alternatives
Why This Product
- Engineered specifically for I-joists - the PAN design and Funnel Flange work together to address the unique installation and splitting challenges of engineered wood members, resulting in faster installs with fewer callbacks
- Built-in flexibility for varying load requirements - optional triangle nail holes allow the same hanger to be adapted for increased uplift applications, reducing the need to source a separate connector for higher-demand situations
- G90 galvanized coating for lasting durability - the zinc galvanized finish resists corrosion in the conditions typical of framing installations, helping the connection maintain its integrity over the life of the structure
- A practical, code-friendly alternative to welded hangers - supports standard 90 deg. I-joist-to-header connections with conventional fasteners and optional PAT fastening for steel headers, making it a versatile choice across a range of residential and commercial framing projects

Frequently Asked Questions
What type of connection is the Simpson MIT314 designed to support?
The Simpson MIT314 is designed to support standard 90 deg. connections of I-joists to headers, making it suitable for engineered wood framing applications.
What fasteners are required to install the MIT314?
Install with 0.162 in. x 3-1/2 in. nails in the header and 0.148 in. x 1-1/2 in. nails in the joist.
What is positive-angle nailing (PAN) and why does it matter?
Positive-angle nailing (PAN) is a design feature specifically created for I-joists that minimizes splitting of the flanges while allowing nailing from a better angle to save time. Importantly, the nail hole material is not removed with this method, preserving the structural integrity of the connection.
Can the MIT314 be used in applications requiring increased uplift capacity?
Yes. Optional triangle nail holes on the MIT314 may be used for increased uplift capacity; however, optional uplift nailing requires the addition of properly-secured web stiffeners.
