RAM Mounts Rail Clamp Ball Base for 1.25 inch - 1.875 inch Rails, Black Aluminium

The RAM-D-271U-12 round pipe base is a rail clamp designed to attach to round tubing with diameters from 1.25" to 1.875". Constructed with a black aluminium body and a 2.25" (5.71 cm) rubber ball, this base serves as a foundation for RAM ball-and-socket mounting systems, providing a stable connection between the rail and compatible RAM arms or device holders.

Advantages

The aluminium construction offers corrosion resistance and reduced weight compared with heavier metals, while the rubber ball provides vibration damping and secure engagement with RAM socket components. The clamp accommodates a range of standard rail diameters, enabling flexible placement on tubes and round rails.

Suitable for

• Mounting device arms on boat rails and marine tubing
• Attaching electronics or accessories to bicycle or motorcycle handlebars within the specified diameter range
• Securing mounts to industrial or workshop round rails and pipework

How to use

Position the clamp around the round rail or tubing within the compatible diameter range, then tighten the clamp fastener until the base is held firmly in place. Attach a RAM arm or socket component to the rubber ball by enclosing the ball within the corresponding socket and securing the socket's locking hardware to achieve the desired orientation. Confirm all fasteners are tightened and the mounted device is stable before use.

Recommendations

Check the rail diameter before installation to ensure compatibility. Periodically inspect clamp fasteners and the rubber ball for wear or degradation, especially in marine or outdoor environments, and replace components as needed to maintain a secure mount.
