The RAM® Universal Wheelchair Base is a feature-rich mounting platform supporting any phone, tablet or cup holder for any wheelchair armrest or seat track. With the turn of a single knob the user can swivel the entire mounting system in and out of position without having to adjust any other mounting components. A quick release button is integrated into the base which allows the user to easily remove or insert the mount from the chair; also, a great option for swapping out one device mount for another. The compact design of the RAM® Universal Wheelchair base keeps the mounting system within the chair's armrest width, offering peace of mind when navigating through tight spaces and doorways. All RAM® mounting components are backed by a lifetime warranty.
