High-Performance, Backer-Free Hanger for I-Joist to I-Joist Connections

The Simpson Strong-Tie HITB Series is a top flange joist hanger designed to simplify and reinforce I-joist to I-joist connections—without the need for backer blocks. With models such as HITB200/47 through to HITB300/91, this range supports a variety of joist depths and widths, delivering structural integrity, installation efficiency, and code-compliant performance for engineered floor systems.

Key Features

Backer-Free Design
Eliminates the requirement for backer blocks when fixing into I-joist headers, reducing material costs and installation time.
Bottom Flange Location Tabs
Help accurately position the hanger on the header, holding it in place during fixing for quicker, hands-free installation.
Open Top Flange
Improves accessibility for nailing and simplifies installation on-site—ideal for use in tight floor cavity spaces.
Optional Fixing Holes
Additional nail holes provided to boost download and uplift capacity, offering structural flexibility as needed.
Steel Reinforced Strength
Manufactured from pre-galvanised mild steel for strong, corrosion-resistant performance in protected structural environments.

Benefits

Reduces Installation Time
No backer blocks mean less preparation and faster on-site joist integration.
Improves Build Accuracy
Integral tabs and top flanges ensure precise alignment and consistent fit, reducing call-backs and structural errors.
Flexible Structural Capacity
Optional nailing patterns allow performance to be tailored to the specific load demands of the application.
Ideal for Multi-Header Systems
Supports use on multi-joist headers (using MJC connectors or filler blocks) where greater bearing width is needed.

Installation Guide

Prepare Header:
Connect supporting I-joists using MJC connectors or filler blocks per the manufacturer’s guidance.
Position the Hanger:
Place the HITB hanger against the I-joist header. Ensure bottom flange tabs are tight to the underside of the bottom chord.
Secure Face and Bottom Flanges:
Fill round and obround face holes with nails. Drive nails into bottom flange holes.
Fix Top Flange:
Flatten the open flanges onto the top chord of the header. Use a minimum of four nails per flange (two front, two rear).
Secure Bottom Chord Tabs:
Bend tabs over the top face of the bottom chord, and nail through obround holes.
Install Carried Joist:
Insert joist into stirrup. Nail through the designated round and obround holes into the joist face.

⚠️ Note: Web stiffeners are mandatory when using the HITB and HITB-LT to prevent web buckling under load.

Applications

Engineered timber floor systems (I-joist to I-joist)
Multi-header I-joist framing
Joist connections in residential or commercial timber structures
Floor assemblies requiring reduced fix complexity

Important Notes

Always follow Simpson Strong-Tie’s technical documentation for fastener types, spacing, and load capacities.
For weld-on or steel-to-joist solutions, alternative hanger types should be considered.
Not suitable for unprotected outdoor use without additional corrosion treatment.
