RAM® Tough-Claw Mount Large with 1" Diameter Rubber Ball (RAP-B-401) by RAM Mounts

When the pavement gets rough or the trail turns to whoops, a cheap mount is the first thing to fail. The RAM® Tough-Claw Mount Large with 1" Diameter Rubber Ball (RAP-B-401) is a tool-free clamp base with rubber-padded jaws and a 1" B-size ball, built to grab round, square and odd-shaped tubes, and it is built to RAM Mounts’ proven ball-and-socket standard so it stays put mile after mile.

At Witchdoctors we stock genuine RAM Mounts parts with the same part numbers RAM uses, so you can build a new setup, replace a worn piece or expand the system you already own with confidence.

Why Choose the RAM® Tough-Claw Mount Large with 1" Diameter Rubber Ball

The Tough-Claw is the base riders reach for when a bar is not perfectly round or when they want to move the mount between vehicles. It installs and comes off by hand in seconds, so you can mount on a roll cage, grab bar, rack or handlebar without drilling or tools.

It uses a large Tough-Claw™ clamp base (about 1" to 2.25" outer diameter).

How the RAM Ball-and-Socket System Works

Every RAM mount is built from three interchangeable parts: a base that attaches to your vehicle, a double socket arm, and a holder or accessory for your device. Each base and holder ends in a rubber ball, and the arm’s sockets clamp around those balls when you turn the center knob. The rubber gives the joint grip, lets you set almost any angle, and helps soak up shock and vibration.

Parts only connect within the same ball size, so it pays to know the system:

• A size: 0.75" ball for lightweight devices
• B size: 1" ball, the most popular size for phones, GPS units, cameras and cup holders
• C size: 1.5" ball for tablets and heavier equipment
• D size: 2.25" ball for laptops and heavy-duty loads

This part uses the B-size 1" ball, so it works with all RAM B-size bases, arms and holders.

Materials and Build Quality

RAM builds its mounts from high-strength composite, powder-coated marine-grade aluminum and stainless steel hardware, depending on the part. Composite parts (usually marked with a RAP prefix) are light, strong and rust-proof. Aluminum parts are powder-coated to resist corrosion. Stainless hardware won’t rust in rain, mud, road salt or salt spray, so the mount keeps working season after season.

Fitment and Compatibility

The RAM® Tough-Claw Mount Large with 1" Diameter Rubber Ball is a universal-fit RAM part. It isn’t tied to a model year. Fit depends on the mounting point, such as bar or tube diameter, reservoir screw spacing, thread size or surface type, and for holders on the size of your device.

• Motorcycles, including cruisers, baggers, touring, sport and adventure bikes, with Indian and Victory motorcycles specifically tagged for fit on our site
• Boats, trucks, tractors, mowers and equipment wherever the base can attach

Model years: all years, provided the mounting point matches the specifications above. Not sure of your bar size? Use our Roll Cage / Handlebar Measurement Guide before you order.

Installation

1. Confirm the outside diameter of the tube is within the clamping range.
2. Open the claw, position it on the tube and tighten the knob until the jaws bite firmly.
3. Attach a RAM B-size double socket arm and holder.
4. Check grip again after the first ride.

Most installs take under 15 minutes with basic hand tools. Recheck knob tension and fasteners after your first ride.

Where the RAM® Tough-Claw Mount Large with 1" Diameter Rubber Ball Works Best

• Turn-by-turn navigation on cross-country tours and weekend rides
• Music, intercom and ride-tracking apps within easy reach
• Commuting with your phone visible and secure

Protecting Your Phone From Vibration

High-amplitude vibration, especially from powerful motorcycle engines, can damage the optical image stabilization and autofocus systems in some smartphone cameras. Apple publishes guidance warning iPhone owners about this. To reduce the risk, keep arms short, use rubber-ball joints like RAM’s, and consider adding a RAM Vibe-Safe™ dampener. RAM notes that reducing vibration does not guarantee full protection, so use your judgment on very high-vibration machines.

Care and Maintenance

• Clean with mild soap and water. Avoid harsh solvents that can dry out the rubber balls.
• Check knob tension and base fasteners periodically, especially on off-road machines.
• Replace worn X-Grip post caps or tethers to keep full grip.
• Inspect rubber balls for cracking after long sun exposure, and replace the part if needed.

Frequently Asked Questions

Will it slip on a roll cage?

When sized correctly and tightened firmly, the rubber jaws hold securely. Check the tube diameter against the clamping range first.

Can I use it on a motorcycle handlebar?

Yes, provided the bar diameter is within range and there is enough clear bar space for the claw.

Is it waterproof?

RAM mounts are built for all-weather use and the hardware resists corrosion. Unless a holder is specifically rated waterproof, your device still needs its own protection from rain and dust.

Will it damage my handlebars or paint?

Rubber-padded contact points and correct hardware torque prevent damage. Do not over-tighten clamps on chrome or painted parts.

What warranty does RAM offer?

RAM Mounts backs its mounts and components with a limited lifetime warranty. Mounted devices are not covered.

Is the RAM® Tough-Claw Mount Large with 1" Diameter Rubber Ball compatible with my other RAM parts?

Yes. It uses RAM’s 1" B-size ball, so it works with any RAM B-size arm, base or holder.
