The Simpson NCA2X8-16 Nailless Compression Bridging from Simpson delivers critical bracing between floor joists, reinforcing the structural continuity of a floor system without a single nail. Installed in pairs, this compression bridging prevents joist rotation and distributes floor loads across multiple joists - making it a reliable choice for builders and remodelers working with nominal 2x8 and 2x14 joists at 16-inch spacing. Precision-formed from 20-gauge steel with a G90 galvanized finish, the NCA2X8-16 offers both lasting durability and installation flexibility, whether you are working in new construction or an existing floor assembly.

Key Features

• Keeps floor system continuity and prevents joist rotation - maintains joist alignment under load, contributing directly to a stable, long-lasting floor structure
• Built-in v-shaped prongs replace nails entirely - eliminates nail squeaks at the source, so the finished floor stays quiet over time without additional fasteners
• Precision-formed into a rigid "V" section - the structural shape locks in compression strength, keeping bridging firm and effective throughout the life of the floor
• Installs before or after sheathing, from the top or bottom - gives contractors the flexibility to complete bridging at any stage of the project, reducing scheduling constraints
• Sized for nominal 2x8 and 2x14 joists at 16-in. spacing - purpose-built dimensions mean no cutting or field modification is needed for compatible joist bays
• Made from 20-gauge steel with G90 galvanized coating - corrosion-resistant construction stands up to the moisture conditions common in floor framing environments

Why This Product

• A nailless design that solves the squeak problem - by using precision-formed prongs instead of nails, the NCA2X8-16 removes the most common cause of floor squeaks in traditionally nailed bridging, giving homeowners and building owners a quieter floor from day one
• True installation flexibility for real job-site conditions - the ability to drive the bridging from the top or bottom and before or after sheathing means work can proceed without being locked into a specific sequence, saving time on both new builds and retrofit projects
• Paired installation maximizes structural performance - using the NCA2X8-16 in pairs distributes floor loads across more than one joist and actively resists rotation, contributing to a stronger, more connected floor system overall
• Domestic G90 galvanized construction built for longevity - 20-gauge steel with a zinc galvanized G90 finish provides corrosion resistance suited to the demands of floor framing, backed by the engineering standards Simpson is known for

Frequently Asked Questions

What joist sizes and spacing is the NCA2X8-16 designed for?

The NCA2X8-16 is designed for nominal 2x8 and 2x14 floor joists with 16-inch spacing. Its bridging length of 15-1/4 in. is sized to fit these specific joist dimensions.

Why is this bridging called "nailless" and how does it stay in place?

Instead of nails, the NCA features precision-formed v-shaped prongs that grip the joist wood securely before a final drive-home blow embeds the prongs deeper for a firm, permanent hold. This nailless design eliminates the nail squeaks that commonly plague traditional bridging installations.

Can the NCA2X8-16 be installed after the subfloor sheathing is already down?

Yes. The NCA2X8-16 may be installed before or after sheathing, and it can be driven in from either the top or the bottom of the joist bay, offering flexibility during both new construction and retrofit projects.

Does the NCA2X8-16 need to be installed in pairs?

Yes. The NCA compression bridging is installed in pairs. Pairing the bridging units is essential to keeping joists in place, preventing rotation, and properly distributing floor loads across more than one joist for maximum structural effectiveness.
