Here is the armrest height adjustment knob for the Shoprider 6Runner 10 and 6Runner 10 Deluxe, Jimmie, Smartie, and Streamer Sport power chairs. These small but vital parts are often lost, so you may want to buy an additional one as a spare.

Note: Shoprider has used several armrest adjustment knob sizes over the years. To be sure about ordering the correct one, please refer to the photo, the Specifications, and the Compatibility list.
