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.
