RAM Rail Mount with 1.5" C-Ball (SKU: RAM-231ZU)

The RAM-231ZU is a versatile rail mounting base featuring a zinc-coated U-bolt and a 1.5" C-size rubber ball, designed to attach securely to round rails, tubing, and frame structures. This mount provides a strong foundation for heavy-duty electronics and accessories, making it ideal for fleet vehicles, heavy machinery, marine installations, and off-road equipment.

The U-bolt accommodates a wide range of rail diameters (0.5" to 1.25"), while the C-ball integrates with RAM’s entire C-size ecosystem of double socket arms, VESA plates, Toughbook docks, and device cradles. Built from corrosion-resistant materials, the RAM-231ZU withstands high vibration, outdoor exposure, and demanding operational environments.
