FAQs

Is this a complete mount? Yes. The Tough-Claw base, short arm and X-Grip cradle are all included — there's nothing else to buy to get your phone onto the bar.

Will the Tough-Claw fit my handlebar? It clamps tool-free to round, square and odd-shaped bars from 15.9mm to 29mm outer diameter, and to flat surfaces up to 29mm thick. Most motorcycle and bicycle bars, aircraft yokes, kayak rails and roll bars sit inside that range — measure yours before ordering.

Will my phone fit with a case on? Measure the width of your phone with the case, sleeve or skin fitted. The X-Grip cradle holds devices from 47.6mm to 82.6mm wide. If you run a large phone, choose the UN10 version of this kit instead.

Short arm or medium arm? This kit uses the short RAM-B-201U-A arm, which holds the phone tight to the bar and suits cramped cockpits and handlebar clusters. The medium-arm version of the same kit gives more reach and a wider range of viewing angles.

Is the tether included? Yes. We'd recommend fitting it for motorcycle, off-road, marine and any other high-vibration use — it's cheap insurance if the phone is ever knocked loose.
