Clamp Ball Base RAM Mounts Tough-Claw Small RAP-400U — black/stainless, width 30 mm, height 122.2 mm

The RAM Mounts Tough-Claw Small Clamp Ball Base (black/stainless) is a compact clamp designed to secure RAM ball-based arms and device holders to round tubes, rails and irregular shapes. With a 30 mm jaw width and an overall height of 122.2 mm, the clamp provides a low-profile, mechanically strong anchor point for cameras, action-sports accessories, GPS units and other small devices. Constructed from stainless steel hardware and a high-strength composite body finished in black, the clamp is intended for demanding outdoor and mobile applications where vibration resistance and quick repositioning are required.

Advantages

The clamp combines stainless steel fasteners with a resilient composite body for corrosion resistance and structural durability. Its narrow 30 mm jaw fits common tubing sizes and irregular mounting surfaces while the integrated RAM ball interface enables secure attachment of standard RAM arms and device holders. The design offers a balance of compact size and holding strength, allowing tool-free tightening and repeated repositioning without loss of clamping force.

Suitable for

• Mounting action cameras to roll bars, bike frames or sport equipment
• Securing GPS units, small displays or telemetry boxes on boats and off-road vehicles
• Attaching lights, sensors or auxiliary accessories to irregular or round rails
• Temporary or semi-permanent setups where frequent adjustment is needed

Key specifications

• Jaw width: 30 mm
• Overall height: 122.2 mm
• Material: composite body with stainless steel hardware
• Finish: black composite exterior with stainless accents
• Mount interface: RAM ball-compatible connection for standard RAM arms and device holders
• Clamping type: adjustable clamp suitable for round and irregular surfaces

How to use

Position the clamp around the tube, rail or irregular surface so the clamping faces seat evenly. Insert and tighten the fastener until the clamp body grips the surface securely but avoid over-torquing stainless hardware. Attach a RAM ball arm or device holder to the ball interface and set the arm to the desired orientation. Make fine adjustments by loosening the clamp or the ball socket, repositioning the device, then re-tightening to lock the assembly in place.

Usage recommendations

Inspect contact surfaces for debris or paint that could reduce grip and ensure bolts are checked periodically for corrosion or loosening. For maximum stability on thin or highly irregular tubes, consider adding a thin protective sleeve between the clamp and the tube to increase contact area and protect surfaces.
