Product Description
The Simpson Adjustable I-Joist Truss Hanger from Simpson is engineered specifically for I-joist applications, featuring extra-long straps that can be field-formed to deliver both height adjustability and top-flange hanger convenience on the job site. Positive-angle nailing is built into the design to help eliminate splitting of the I-joist's bottom flange, making this hanger a reliable and installer-friendly solution for demanding structural connections where precision and load integrity are critical.
Key Features
- Designed specifically for I-joist applications - ensures a proper, code-conscious fit for the framing systems where generic hangers often fall short.
- Extra-long straps for field-forming - allow installers to adjust hanger height on site, reducing the need for pre-ordered custom sizes and keeping projects moving.
- Top-flange hanger convenience - field-formed straps fold over the header to simplify installation and create a secure, stable connection without added hardware.
- Positive-angle nailing design - helps eliminate splitting of the I-joist's bottom flange, protecting structural members and improving connection reliability.
- 18-gauge steel construction with a galvanized finish - provides the structural strength and corrosion resistance needed for long-term performance in demanding framing environments.
Why This Product
- Built for the complexity of I-joist framing - unlike generic hangers, this product is purpose-engineered for I-joist truss applications, addressing the specific load transfer and connection challenges those assemblies present.
- Field-adjustable design saves time and reduces waste - the extra-long, field-formed straps let crews adapt the hanger to varying header heights on site, eliminating delays tied to fixed-dimension alternatives.
- Installer-friendly nailing geometry - the positive-angle nailing feature actively works to protect the I-joist's bottom flange during fastening, reducing the risk of damage that could compromise the structural connection.
- Sourced from a trusted structural connector brand - Simpson has a long-standing reputation in engineered structural hardware, and this hanger reflects that commitment to precision, performance, and field-proven design.

Frequently Asked Questions
Are web stiffeners required when using the THAI5.13/21?
Yes. Web stiffeners are required for all I-joists used with these hangers to ensure proper load transfer and structural integrity.
How far must the strap be field-formed over the top of the header?
For top nailing installations, the strap must be field-formed over the top of the header by a minimum of 21/2" to meet the minimum nailing configuration requirements.
How do I achieve maximum load-carrying capacity with the THAI5.13/21?
Maximum load-carrying capacity is achieved when a total of 20 face nails are used in the THAI straps. Each nail fewer than the maximum requires a corresponding reduction in the allowable load based on nail shear capacity.
How are uplift loads achieved with this hanger?
To achieve uplift loads, the lowest face nails must be filled. Verify that the header can accept the fasteners specified in the load table before installation, and always use all specified fasteners.
