ProX Header is a light gauge steel header that provides horizontal and vertical load support. This pre-engineered metal framing component is designed as a 1- or 2-piece steel header that can be used in lieu of 4- or 5-piece built-up (stud and track) headers in both interior and exterior applications, including door and window openings. It also works at any framed opening in the wall, such as HVAC openings and other wall penetrations.

The ProX Header is made of 20, 18, 16 and 14 gauge (33, 43, 54 and 68 mil) galvanized steel complying with industry-standard ASTM performance criteria for metal stud framing. The members fasten together with No. 8 (interior) or No. 10 (exterior) sheet metal screws (SMS). ProX Header Clips are internal and connect horizontally to vertical members, which leaves a smooth framing substrate for the drywall and finishing trades.
