The Simpson LTB20 19-1/2 in. 22-Gauge Galvanized Tension Bridging is a light tension-type floor joist bridging connector engineered by Simpson to deliver critical bracing between floor joists. Installed in cross pairs, this steel bridging keeps joists in place, prevents rotation under load, and distributes forces across multiple joists to maintain the structural continuity of the entire floor system - making it a reliable choice for residential and light commercial floor framing applications.

Key Features

• Tension-type bridging with maximum nailing flexibility - use as few as two or as many as six nail holes per end, giving installers adaptable options to suit job site conditions
• Staggered nail pattern accommodates 2x8 and 2x10 joists - a single bridging strap works with two of the most common floor joist sizes, reducing the need to stock multiple part numbers
• Keeps floor system continuity and prevents joist rotation - bracing joists laterally helps maintain alignment over time and contributes to a stiffer, more stable floor
• Works only in tension, so must be used in cross pairs - installing two straps in an X-pattern ensures effective bracing in both directions regardless of load orientation
• Made from 22-gauge steel at 19-1/2 in. in length - a consistent, proven profile sized to fit standard joist spacing in typical floor framing
• Galvanized with a G90 zinc coating - provides an extra layer of corrosion resistance to support long-term durability in floor framing environments

Why This Product

• Engineered for structural reliability - Simpson designed the LTB20 specifically to brace floor joists, prevent rotation, and distribute loads across more than one joist, directly contributing to the strength and continuity of the floor system
• Versatile fit for common joist sizes - the staggered nail pattern makes one strap compatible with both 2x8 and 2x10 joists, simplifying procurement and reducing waste on mixed-dimension framing projects
• Flexible installation without sacrificing performance - the option to use between two and six nail holes per end allows contractors to adapt to varying field conditions while meeting installation requirements
• Corrosion-resistant finish built for the long term - the G90 zinc galvanized coating helps protect against corrosion in the enclosed, moisture-variable environments typical of floor framing assemblies

Frequently Asked Questions

Why must the LTB20 be installed in cross pairs?

The LTB works only in tension, meaning it can only resist pulling forces - not compression. Installing two pieces in an X-pattern across adjacent joists ensures that at least one strap is always in tension regardless of the direction of load, providing effective bracing in both directions.

Which joist sizes is the LTB20 compatible with?

The LTB20 features a staggered nail pattern specifically designed to accommodate both 2x8 and 2x10 floor joists, making it versatile for common residential and light commercial floor framing applications.

How many nails are required to install the LTB20?

Installation requires a minimum of two nail holes per end using (2) 0.113 in. x 2 in. nails per end. The design offers maximum nailing flexibility, with the option to use as few as two nail holes on each end and as many as six nail holes on each end.

What corrosion protection does the LTB20 have?

The LTB20 is coated with a G90 zinc galvanized finish, which provides an extra layer of corrosion resistance to help ensure long-term durability in floor framing environments.
