The Simpson NCA2X12-16 Nailless Compression Bridging from Simpson delivers essential structural bracing between 2x12 floor joists, making a critical contribution to the overall strength and stability of a floor system. Installed in pairs, this compression bridging keeps joists in place, prevents rotation, and distributes loads across more than one joist - all without a single nail. Precision-formed v-shaped prongs grip the joist wood securely on initial placement, and a final drive-home blow seats them deeper for a firm, lasting connection that eliminates the squeaking commonly associated with traditional nailed bridging.

Key Features

• Keeps floor system continuity and prevents joist rotation - maintains proper joist alignment throughout the life of the floor, reducing movement and long-term structural degradation
• Built-in prongs eliminate the need for nails - removes a primary source of floor squeaks and speeds up installation by eliminating separate fasteners
• Precision-formed rigid "V" section - provides a strong, stable profile that resists flex and maintains consistent compression between joists
• Installs before or after sheathing, from the top or bottom - offers installation flexibility at any stage of the framing process, saving time on both new construction and retrofit projects
• Sized for nominal 2x12 joists at 16-in. on-center spacing - engineered to fit accurately within the joist bay with a bridging length of 16-7/8 in., ensuring a precise, secure fit
• Made from 18-gauge steel - provides the rigidity and load-transfer performance expected in structural floor bracing applications
• G90 zinc galvanized coating - offers strong corrosion resistance, making this bridging appropriate for use in moisture-prone environments and damp subfloor conditions

Why This Product

• Nail-free installation means a quieter floor, permanently - because the prongs grip directly into the joist wood rather than relying on nails, there is no metal-on-metal contact to work loose over time and cause annoying floor squeaks
• Structural performance built into the design - installed in pairs, this compression bridging distributes floor loads across multiple joists and prevents rotation, contributing directly to the integrity of the entire floor system rather than just individual members
• Stage-of-construction flexibility reduces scheduling pressure - the ability to drive bridging from the top or bottom, before or after sheathing is applied, means installation can happen whenever it fits the job sequence without requiring a separate return visit
• G90 galvanized steel construction extends service life - the corrosion-resistant finish means this bridging holds up in the damp conditions that floor framing is frequently exposed to during and after construction

Frequently Asked Questions

How does the NCA2X12-16 attach to floor joists without nails?

The NCA2X12-16 features precision-formed v-shaped prongs built directly into the connector. These prongs provide a secure grip during initial placement, and a final drive-home blow seats them deeper into the joist wood for a firm, nail-free connection that eliminates the squeaking associated with traditional nailed bridging.

Can this bridging be installed after the subfloor sheathing is already in place?

Yes. The NCA2X12-16 may be installed either before or after sheathing is applied, and it can be driven from the top or the bottom of the joist bay, offering flexibility at any stage of the floor framing process.

Is this bridging suitable for use in damp or moisture-prone environments?

The NCA2X12-16 is manufactured from 18-gauge steel with a G90 zinc galvanized coating, which provides a strong layer of corrosion resistance, making it appropriate for use in conditions where moisture exposure is a concern.

What joist size and spacing is the NCA2X12-16 designed for?

This bridging is specifically sized for nominal 2x12 floor joists set at 16-inch on-center spacing. The bridging length is 16-7/8 inches to fit accurately within that bay width.
