I-joist blocking

PatriciaCranberry | Posted in General Questions on

Laying out shop lighting..just some 4′ led strip lights. Can I use the attached method to wire my fixtures right where they need to be? I see install guidelines for I joists that say “no nailing the flange” how would these small blocking pieces be secured to the i-joist….wanting to use dense pack after all plumbing and electrical is done so I’m not wanting to create a full blocking from bottom of 2nd floor subfloor to top of 1st floor ceiling.

    The illustration below comes from an installation guide published by Weyerhaeuser. The illustration shows that it's possible to install fasteners through the OSB web as well as through the flange (because the continuous strapping shown in the illustration appears to be fastened to the flange).
