About this detail

Code-compliant pipe and conduit penetrations pass through cold-formed steel wall studs using notched track reinforcement. The wall section establishes allowed and prohibited penetration zones based on stud height, limiting penetrations to the middle third of the stud span with specific top and bottom clearances. Exploded isometric and isometric views detail the notched track matching the depth, width, and gauge of the stud, secured with five number 10 self-tapping sheet metal screws at each flange above and below the penetration and six number 10 screws to the web. A minimum stud size schedule dictates the smallest acceptable stud depths and gauges, prohibiting penetrations in studs smaller than specified.
