RAM Mounts Double U-Bolt Rail Mount for Smaller Rails, Black, model RAM-101U-235

The RAM Mounts Double U-Bolt Rail Mount for Smaller Rails (black) is a compact mounting base designed to clamp securely to narrow round or square rails. Constructed from corrosion-resistant materials and finished in black, this rail mount accepts compatible RAM arms or ball-and-socket attachments via its dual U-bolt clamping system. With a moderate weight and a low-profile footprint, it is intended for applications that require a stable, space-efficient rail attachment point on boats, vehicles, or industrial equipment.

Advantages

This double U-bolt rail mount delivers a stable clamping solution for smaller-diameter rails, providing reliable retention through two U-bolts that distribute load and reduce rotation. The black finish offers discreet appearance and additional surface protection. Its compact size minimizes obstruction on narrow rails while still permitting mounting of a range of compatible arms and devices. The design is suitable for repeated installation and removal without complex tools.

Suitable for

• Attaching device arms or holders to small-diameter boat rails and lifelines
• Mounting accessories on vehicle roll bars, grab rails or tubular frames
• Securing instruments or fixtures to industrial handrails and racks
• Temporary or semi-permanent setups where a removable rail mount is needed

When it may not be suitable

This mount is intended for smaller rails and may not fit or clamp safely to very large-diameter tubing or irregularly shaped structural members. It is not a universal solution for heavy structural loads; for high-load or safety-critical connections, a purpose-designed heavy-duty or welded mounting solution should be considered. Confirm rail dimensions and clearance before installation.

Key specifications

• Mount type: double U-bolt rail clamp for smaller rails
• Finish/color: black
• Material: corrosion-resistant metal and hardware components
• Weight: approximately 662.2 g
• Compatibility: fits narrow round or square rails and accepts compatible RAM arms or ball-and-socket attachments

How to use

Position the clamp around the rail so the two U-bolts sit evenly on either side of the tubing, align the base with the desired mounting orientation, then secure the nuts onto the U-bolts and tighten incrementally to achieve a snug fit. Attach the compatible RAM arm or ball-and-socket component to the mount’s attachment point and verify alignment. Check torque and stability after initial installation and periodically during use, especially in marine or vibration-prone environments.

What to consider before purchase

• Confirm the outside diameter or cross-section of the rail to ensure fit with a double U-bolt clamp designed for smaller rails
• Ensure compatibility with your chosen RAM arm or attachment type
• Assess exposure to marine or corrosive environments and consider additional corrosion protection if required
• Verify available clearance on and around the rail for installation and device articulation

Usage recommendations

For best results, hand-tighten the U-bolt nuts and then use a torque wrench or appropriate tool to bring them to an even, moderate torque. Regularly inspect the mount, fasteners and contact surfaces for loosening or corrosion, and tighten or replace components as needed to maintain secure attachment.
