The NCA provides bracing between floor joists as a critical contribution to the structural strength of a floor. Installed in pairs, this nailless compression bridging keeps joists in place and prevents them from rotating while distributing loads over more than one joist. The NCA features precision-formed v-shaped prongs, in place of nails, to provide a secure grip before the drive-home blow for deeper prong penetration.
Galvanized for corrosion resistance
Keeps floor system continuity and prevents joist rotation
Installs with built-in prongs that eliminate nail squeaks
20 gauge (except NCA2x12-16 — 18 gauge)
Support floor joists with a depth-to-thickness ratio of six or more with bridging at intervals not exceeding 8'. If span is greater than 8', install on 2x8 or larger joists. If span is greater than 16', use more than one pair.
Tension bridging works only in tension, so must be used in cross pairs.
Install bridging tightly; loose installation may allow floor movement.
May be installed before or after sheathing, from the top or bottom. Simply locate the bend line approximately 1" from the joist edge.
Has nail holes in one end for use if a prong is bent during installation. Fully seat nails (0.131" x 1 1/2") if they are used; otherwise, they may lead to squeaks.
