The Simpson TB27 27" Galvanized Tension Bridging by Simpson Strong-Tie is a tension-type bridging connector built to brace floor joists, prevent rotation, and distribute loads across multiple joists for a stronger, safer floor system. Engineered and tested to meet the highest quality standards, this joist bridging is the proven choice of engineers and contractors on residential and commercial framing projects alike.

Key Features

• Tension-type bridging with maximum nailing flexibility; use just two of the seven nail holes at each end - gives installers the freedom to position fasteners where framing conditions require, without sacrificing a secure, code-ready connection
• Easy to install - straightforward installation reduces labor time on the job site, keeping floor framing projects on schedule
• Engineer trusted and contractor proven - backed by Simpson Strong-Tie's rigorous engineering and testing, so you can rely on consistent, predictable performance in structural applications
• 20-gauge steel construction - provides the structural integrity needed for effective joist bridging while keeping the connector lightweight and easy to handle
• Galvanized (G90) zinc coating for extra corrosion resistance - protects the steel in demanding floor framing environments, supporting long-term durability in the assembly

Why This Product

• Built-in nailing flexibility reduces installation headaches - with seven nail holes at each end and only two fasteners required per end, this tension bridging adapts to real-world framing conditions rather than forcing you to work around a rigid design
• G90 galvanized protection you can count on - the zinc galvanized finish delivers extra corrosion resistance, making this floor joist bridging a dependable long-term choice in structural assemblies where moisture exposure is a concern
• Designed and manufactured to satisfy building code requirements - Simpson Strong-Tie connectors are engineered and tested to perform, making the TB27 a straightforward choice for projects that must meet code compliance standards
• Made in the United States to the highest quality standards - domestic production under Simpson Strong-Tie's quality controls ensures the consistent material and dimensional accuracy that engineers and contractors depend on across every installation

Frequently Asked Questions

How many nail holes does the TB27 have, and how many are required for installation?

The TB27 features seven nail holes at each end, but only two fasteners per end are required for a proper installation - specifically two 10d x 1-1/2 in. fasteners per end. This design provides maximum nailing flexibility.

What gauge steel is the TB27 made from, and what corrosion protection does it have?

The TB27 is made with 20-gauge steel and features a G90 zinc galvanized coating, which provides extra corrosion resistance for long-lasting performance in floor framing applications.

How does tension bridging work, and why must it be installed in pairs?

Tension bridging works only in tension, meaning it resists forces by pulling rather than pushing. Because of this, TB bridging must be installed in cross pairs so that each piece can handle tension forces in the appropriate direction, keeping joists in place and preventing rotation under load.

Is the Simpson TB27 suitable for use on professional construction projects requiring code compliance?

Yes. Simpson Strong-Tie connectors are engineered and tested to perform and are manufactured to the highest quality standards. They are suitable for projects that must comply with building codes and are the proven choice of engineers and contractors.
