Frequently Asked Questions

What type of bridging is the Simpson TB30, and how does it work?

The TB30 is a tension-type bridging connector. Because it works only in tension, it must be installed in cross pairs. When installed tightly in pairs between floor joists, it keeps joists in place, prevents rotation, and helps distribute loads over more than one joist for a stronger, more stable floor system.

How many nail holes does the TB30 have, and how many fasteners are required?

The TB30 features seven nail holes at each end for maximum nailing flexibility, but only two of those nail holes need to be used at each end. Installation requires two 10d x 1-1/2 in. fasteners per end.

What corrosion protection does the TB30 have?

The TB30 is made with 20-gauge steel and features a Zinc Galvanized G90 coating, which provides extra corrosion resistance to help ensure long-lasting performance in floor framing applications.

Who manufactures the TB30, and can it be trusted for structural applications?

The TB30 is manufactured by Simpson Strong-Tie, a brand whose connectors are engineered, tested, and manufactured to the highest quality standards. Simpson Strong-Tie connectors are the choice of engineers and contractors for projects that must meet building code requirements and structural performance standards.
