MiTek Bridging

O The O series spans three joists in under/over installation. Prong teeth in the center help reduce nailing.
N The N series spans two joists per unit. Can be used for bridging or bracing I-Joists. See Joist Installations table.Materials:See Load TableFinish:G90 galvanizingInstallation

• Use specified fasteners in models with fastener requirements.
• For all models Bridging should be installed on floor joists with a nominal depth-to-thickness ratio of 5 to 6 or more (2015 National Design Specification for Wood Construction; Section 4.4.1). Bridging units should be installed in pairs at intervals of 8-ft or less. Bridging pairs should form an X between joists; leave a slight space between the units to avoid noise-generating contact. Follow specific installation instructions below for particular models.
• Install prior to subfloor sheathing. Use (2) 8d x 1-1/2 nails at each end. Fully seat nails to avoid any movement against the bridging and subsequent floor noise.
