The Simpson LTB40 39 in. 22-Gauge Galvanized Tension Bridging is a light tension bridging solution from Simpson Strong-Tie engineered to provide critical bracing between floor joists. Installed in cross pairs, this bridging keeps joists firmly in place, prevents rotation, and distributes loads across more than one joist - resulting in a stronger, more stable floor system for residential and light commercial framing applications.

Key Features

• Tension-type bridging with maximum nailing flexibility - use as few as two nail holes or as many as six nail holes on each end, so you can adapt installation to your specific framing conditions without sacrificing holding strength
• Staggered nail pattern accommodates 2x8 and 2x10 joists - a single bridging piece works across the two most common residential floor joist sizes, reducing the need to stock multiple bridging products
• Keeps floor system continuity and prevents joist rotation - maintains proper joist alignment over time, which helps protect flooring surfaces above from movement, squeaking, and uneven wear
• Must be used in cross pairs - because the LTB works only in tension, installing two pieces in an X-pattern between joists is required for the bridging to function as intended and deliver full structural benefit
• Made from 22-gauge steel - provides a reliable strength-to-weight ratio that makes handling and positioning between joists straightforward during installation
• G90 zinc galvanized finish - delivers extra corrosion resistance to help the bridging maintain its structural integrity over the life of the floor assembly

Why This Product

• Engineered for real-world nailing flexibility - with two to six usable nail holes per end, installers are not locked into a rigid fastening pattern, making the LTB40 adaptable to varying field conditions without compromising the connection
• One product, two common joist sizes - the staggered nail pattern is specifically designed to fit both 2x8 and 2x10 framing members, so contractors working with mixed or unspecified joist stock can rely on a single bridging solution across the job
• Built-in corrosion protection for long-term performance - the G90 galvanized coating goes beyond basic steel finishes, helping the bridging resist moisture-related degradation in typical floor framing environments where bare steel would be vulnerable
• Supports load distribution across the entire floor system - by bracing joists in cross pairs and preventing rotation, the LTB40 helps spread loads over multiple joists rather than concentrating stress on a single member, contributing to overall floor stiffness and stability

Frequently Asked Questions

Can the LTB40 be used as a single piece of bridging, or does it require a partner?

Because the LTB works only in tension, it must be used in cross pairs. A single LTB40 alone will not provide adequate bracing - two pieces must be installed in an X-pattern between joists to function as intended.

Which joist sizes is the LTB40 compatible with?

The LTB40 features a staggered nail pattern specifically designed to accommodate both 2x8 and 2x10 joists, making it suitable for common residential and light commercial floor framing applications.

How many nails are required to install the LTB40?

Installation requires (2) 0.113 in. x 2 in. nails per end as the minimum fastening. However, the LTB40 is designed for maximum nailing flexibility, offering the option to use as few as two nail holes on each end and as many as six nail holes on each end.

What type of corrosion protection does the LTB40 have?

The LTB40 is coated with a G90 zinc galvanized finish, which provides extra corrosion resistance to help the bridging maintain its structural integrity over time in typical floor framing environments.
