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 2x8 and 2x10 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.

Material: LTB - 22 gauge; NCA and TB - 20 gauge (except NCA2x12-16 - 18 gauge).

Finish: Galvanized

Installation:

Code Reference: IRC 2003/2006, R502.7.1
