RAM® Double U-Bolt Ball Base for 1"–1.25" Rails - C Size

This RAM U-bolt ball base is designed for mounting to round rails, bars, or similar tubular structures. It includes a C Size 1.5" (3.8 cm) RAM ball, creating a secure connection point for compatible RAM double socket arms.

The U-bolt design clamps the base around the rail and helps spread the holding force across the mounting area. This is useful when a RAM mount needs to be attached to a boat rail, frame section, handlebar, or another round mounting point.
