This square shower arm comes with an updated square escutcheon flange that includes an anti-scratch O-ring structure, a key improvement over standard basic shower arms. Both the shower arm itself and its matching flange are crafted from heavy-duty solid brass, ensuring long-lasting, corrosion-resistant performance. The 6-inch-long shower arm uses 1 inch by 1 inch solid brass pipe, while the flange itself measures 2.4 inches by 2.4 inches. Both ends of the arm feature soldered 1/2 NPT tapered threads, which create tight, leak-proof connections for standard residential shower systems. Before beginning installation, users should verify the mounting hole size to confirm this shower arm will fit correctly in their existing setup. If you have questions about the installation process, you can reach out to relevant support resources for guidance. This piece works well for either upgrading an old shower arm or replacing worn-out ones, offering a sturdy, low-maintenance option that helps prevent scratches on surrounding wall or tile surfaces during both installation and daily use.
