RG-4X Pro is an upgraded version of the RG-4X, developed for long-term, heavy-duty pipe roll grooving applications. While retaining all the proven advantages of the original 4X platform, the Pro version focuses on structural reinforcement and durability to better match continuous and high-load working conditions. The original support legs are replaced by a reinforced frame-style base with an integrated storage cabinet, improving overall stability and easier tool and accessory storage. The roll grooving assembly has been enlarged for higher durability and more controlled groove forming, while the pipe stand is strengthened to handle heavy steel pipes. Upgraded positioning rollers further help prevent pipe drifting during grooving.
