The Simpson ITS Galvanized Top-Flange Joist Hanger for 1-3/4 in. x 16 in. Engineered Wood from Simpson redefines what a top-flange hanger can do for engineered wood framing. Designed specifically for I-joist connections to headers, this innovative hanger installs faster and uses fewer nails than any other EWP top-flange hanger on the market. The Strong-Grip seat and Funnel Flange features work together to allow standard I-joist installation without requiring joist nails, cutting labor time and delivering the lowest installed cost available in its category.

Key Features

• Strong-Grip seat accommodates flange thicknesses from 1 1/8 in. to 1 1/2 in. - firmly secures a wide range of I-joist flange sizes without additional hardware or adjustment, giving installers confidence across varying engineered wood products.
• No joist nailing required for standard I-joist installation without web stiffeners - eliminates a time-consuming step, speeding up the framing process and reducing overall labor costs on the job site.
• Sized precisely for 1-3/4 in. x 16 in. I-joists - the exact fit ensures a structurally sound, code-compliant connection with no guesswork or field modifications needed.
• Formed from 18-gauge steel - provides the structural strength needed to reliably transfer loads from joist to header in residential and light commercial framing applications.
• Zinc Galvanized G90 coating - delivers enhanced corrosion resistance, making this hanger suitable for applications where moisture exposure is a concern and helping ensure long-term performance.

Why This Product

• Faster installation with fewer fasteners - the combination of the Strong-Grip seat and Funnel Flange design means standard I-joist installation requires no joist nailing, so crews can move through framing faster without sacrificing connection integrity.
• Purpose-built for engineered wood products - unlike generic hangers, this top-flange I-joist hanger is engineered specifically for EWP applications, ensuring a precise, reliable fit for 1-3/4 in. x 16 in. I-joists used in modern construction.
• Lower total installed cost - fewer required nails and quicker placement directly reduce both material and labor expenses, making this hanger a practical choice for production framing and cost-conscious projects.
• Trusted Simpson corrosion protection - the G90 zinc galvanized finish goes beyond standard coatings, providing added durability in framing environments where long-term structural integrity matters.
