Top-Flange Joist Hangers — I-Joist and Structural Composite Lumber Hangers

Strong Frame Moment Frame

Simpson Strong Tie offers several top flange hanger options for attaching joists to the Strong Frame moment frame.

US Patent 8,250,827

ITS — The ITS installs faster and uses fewer nails than any other EWP top‑flange hanger. The Strong‑Grip™ seat enables standard joist installation without joist nails resulting in the lowest installed cost.

HIT Installation on a Strong Frame Beam with Preinstalled Nailers

MIT/HIT — These joist hangers feature positive-angle nailing, which allows the nail to be driven at approximately 45° into the joist flange. This minimizes splitting of the flanges while permitting time‑saving nailing from a better angle.

US Patent 7,334,372
BA Installed on a Strong Frame Beam with Preinstalled Nailers Using Minimum Nailing
