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 compontents are backed by a lifetime warranty.
