RAM MOUNTS RAM-B-231Z-2U base med U-bøjle & UTV-rem - sort

Out on the trail, your phone or GPS needs to stay put. The RAM-B-231Z-2U base gives you a rock-solid anchor on round or square rails, bars, and tubes. Built from marine-grade aluminum and a high-strength composite, this black base shrugs off vibrations, weather, and spray. Use the included U-bolts for diameters from 0.5 to 1.25 inches, or strap it onto larger structures from 1.5 to 3 inches. It's the foundation for any RAM B-size arm and cradle—on motorcycles, ATVs, UTVs, boats, or wheelchairs.
