The Simpson Strong-Tie TBE4 Truss Bearing Enhancer is a structural connector engineered specifically for use with 2x4 nominal top plates in bearing-limited conditions. Where standard bearing capacity falls short, this connector transfers load from the truss or girder directly to the plates, while also delivering exceptional uplift capacity - giving builders and engineers a reliable, code-compatible solution for demanding framing applications. Designed and manufactured by Simpson Strong-Tie, the connector reflects the same engineering rigor and quality standards that professionals depend on across residential and commercial construction.

Key Features

• Load transfer for bearing-limited conditions with exceptional uplift capacity - directly addresses situations where standard bearing is insufficient, reducing the risk of structural deficiencies without requiring complex workarounds.
• Replaces nail-on scabs and eliminates the need for an additional ply - simplifies installation and delivers superior load transfer compared to traditional scab methods, saving time and material on the job site.
• One size fits any number of girder plies - a single connector handles single-ply and multi-ply girder assemblies alike, reducing the need to stock multiple connector sizes.
• Made from 18-gauge steel - provides the structural strength required for truss bearing applications while keeping the connector lightweight and easy to handle during installation.
• Zinc Galvanized (G90) coating - adds a layer of corrosion resistance that helps protect the connector's integrity over the long term in structural environments.
• Engineer trusted and contractor proven by Simpson Strong-Tie - backed by the testing, engineering, and quality standards that make Simpson Strong-Tie the go-to choice for structural connectors across the construction industry.

Why This Product

• A smarter alternative to nail-on scabs - rather than relying on scab attachments that deliver lower load transfer, this truss bearing connector provides a purpose-built solution that performs consistently and meets the demands of bearing-limited framing conditions.
• Versatility across girder configurations - because one size works with any number of girder plies, the TBE4 adapts to a wide range of framing assemblies without requiring a different connector for each application.
• Built-in corrosion protection for lasting performance - the G90 galvanized finish guards against corrosion, making this connector a dependable long-term component in structural connections where durability matters.
• Engineered and quality-tested by Simpson Strong-Tie - this connector comes from a manufacturer whose products are designed to help structures meet building code requirements, giving engineers, contractors, and builders confidence in every installation.

Frequently Asked Questions

What is the purpose of the Simpson TBE4 Truss Bearing Enhancer?

The TBE4 is designed to transfer load from the truss or girder to plates in bearing-limited conditions. It also provides exceptional uplift capacity, making it a reliable solution where standard bearing capacity is insufficient.

What does the TBE4 replace in a typical installation?

The TBE4 replaces nail-on scabs that provide lower load transfer, or in some cases, an additional ply when needed for bearing. This simplifies the installation process while delivering superior performance.

Will the TBE4 work with girders that have multiple plies?

Yes. One size works with any number of girder plies, so the TBE4 is a versatile solution regardless of how many plies your girder assembly requires.

What material and corrosion protection does the TBE4 have?

The TBE4 is made from 18-gauge steel and features a Zinc Galvanized (G90) coating, providing extra corrosion resistance to help ensure long-term durability in structural applications.
