RAM Mounts dubbele U-bout kogelbasis voor 1,25 inch – 1,5 inch rails

The RAM-235-1U Double U-Bolt Ball Base attaches to round rails with diameters from 1.25" to 1.5" and provides a 1.5" diameter ball for mounting compatible RAM arms and device holders. Constructed from aluminum with a black finish and supplied with two zinc-coated U-bolts, the base is intended for secure attachment on vehicle or marine rails where a standard RAM 1.5" ball interface is required.

Advantages

The double U-bolt design clamps around rails of different thicknesses between 1.25" and 1.5" without needing additional adapters. The aluminum construction and black finish offer corrosion resistance and reduced weight, while the included zinc-coated U-bolts provide durable clamping hardware. The standard 1.5" ball interface ensures compatibility with a wide range of RAM arms and device holders.

Suitable for

• Mounting phone or tablet holders on boat rails
• Securing GPS units or cameras to vehicle roll bars
• Attaching accessories to bicycles or motorcycles with compatible rails

How to use

Position the double U-bolt base around the rail so the ball sits where you want the device to be located. Place the U-bolts over the rail and align the base plate, then secure the nuts on the zinc-coated U-bolts and tighten evenly until the base is firmly clamped to the rail. Attach a compatible RAM arm or holder to the 1.5" ball following the arm/holder manufacturer's instructions.

Recommendations

Check all fastenings periodically and retighten as needed, especially in marine or high-vibration environments. Use the specified rail diameter range (1.25"–1.5") to ensure proper fit and clamp strength.
