The cup holder for Quantum power chairs with Tru-Balance 3 seating has been designed to mount securely where other cup holders cannot. This cup holder can be mounted on any T-slot channel on the Tru-Balance 3 armrest , side rails, or accessory bar. The T-slot accessory block and instructions are included.
It was easy to install and fit perfectly. I enjoy having a carrier for my drink.
Perfect replacement. Price more in line than other suppliers.
