Product Overview
This OFFO Extra Large Shower Arm Flange is a precision-engineered replacement designed for universal compatibility with most brands of shower arms. With an outer diameter of 3.5 inches and inner hole size of 13/16 inch (21mm), it fits standard 1/2-inch IPS shower arms.

Ideal for DIY enthusiasts or professional installers seeking reliable, long-lasting components.
