NCA/TB/LTB Bridging

Share This Post:


NCA — nailless installation eliminates callbacks for nail squeaks. Designed for secure grip before the drive-home blow, and deeper prong penetration. Precision-formed into a rigid “V” section.

TB — tension-type bridging with maximum nailing flexibility. Use just two of the seven nail holes at each end.

LTB — staggered nail pattern accommodates 2×8 and 2×10 joists. Use just two of the six nail holes at each end. LTB40 has rigid prongs that install easily into the joist, and embossments that allow crisp bends.


  • LTB — 22 gauge; NCA and TB — 20 gauge (except NCA2x12-16 — 18 gauge)


  • Galvanized


  • 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 2×8 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.
  • NCA may be installed before or after sheathing, from the top or bottom. Simply locate the bend line approximately 1″ from the joist edge.
  • NCA 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.
  • TB requires two 0.148″ x 1 1/2″ fasteners per end.
  • LTB requires two 0.113″ x 2″ nails per end.
