Simpson Strong-Tie offers a dedicated range of top-flange I-joist hangers that meet the unique needs of I-joists while offering superior performance and ease of installation.
The innovative ITS sets the standard for engineered wood top-flange hangers. The ITS installs faster and uses fewer nails than any other EWP top-flange hanger. The Strong-Grip™ seat and Funnel Flange™ features allow standard joist installation without requiring joist nails, resulting in the lowest installed cost. The Strong-Grip seat firmly secures I-joists with flange thicknesses from 1 1/8" to 1 1/2".
MIT/HIT — Positive-Angle Nailing (PAN)
PAN is specifically designed for I-joists when used with the MIT or HIT. With PAN, the nail hole material is not removed, but is formed to channel and confine the path of the nail at approximately 45°. PAN minimizes splitting of the flanges while permitting time-saving nailing from a better angle. See top-flange hanger tables.
Refer to joist manufacturer's literature or appropriate Simpson Strong-Tie Connector Selection Guide for actual joist sizes.
ITS — 18 gauge; MIT, HIT — 16 gauge
