Base de soporte RAM Mounts con doble abrazadera en U y rótula para barras de 1"–1,25", rótula de 3,81 cm, aluminio, negro

The RAM-235U is a double U-bolt ball base designed to secure RAM arms and accessories to round rails with diameters between 1" and 1.25". It features a 1.5" (3.81 cm) diameter ball and is constructed from aluminium with a black finish. Two stainless steel U-bolts are included to clamp the base firmly to the rail, offering a corrosion-resistant mounting point suitable for marine, vehicle, and industrial environments.

Advantages

The aluminium construction provides a balance of strength and reduced weight, while the black finish offers basic surface protection. The 1.5" ball is compatible with standard RAM arm components, enabling modular positioning and adjustment. Inclusion of two stainless steel U-bolts ensures a secure clamp to round rails and improves resistance to corrosion in wet or outdoor conditions.

Suitable for

• Mounting RAM arms and accessories to boat rails
• Vehicle roll bars and tubular frames with 1"–1.25" diameter rails
• Industrial tubing and fixtures requiring a stable ball-mount point

Key specifications

• Ball diameter: 1.5" (3.81 cm)
• Compatible rail diameter: 1" to 1.25"
• Base material: aluminium
• Finish: black
• Included fasteners: two stainless steel U-bolts

How to use

Position the double U-bolt base over the round rail so the ball is oriented toward the desired mounting direction. Place the stainless steel U-bolts around the rail and feed them through the base, then secure with the provided nuts and washers, tightening evenly to clamp the base without deforming the rail. Attach a compatible RAM arm or accessory to the 1.5" ball according to the arm manufacturer’s instructions, then adjust the arm position and tighten its socket hardware to lock the orientation.

Recommendations

For long-term outdoor or marine installations, periodically inspect and retorque the U-bolt fasteners and check for corrosion on mating hardware. Use appropriate thread-locking compound if frequent vibration is present, and avoid overtightening to prevent damage to the rail or base.
