The width adjustable lower arm tube for Invacare AVIVA FX and Pronto series power chairs is a 90 degree elbow bracket that allows the user to slide the armrests in or out to suit their needs. It is available in a left side or a right side configuration.
The armrests on power chairs generally take a lot of abuse from scrapes, scratches, and overall running into things. If your Invacare Pronto has suffered a bent bracket as a result, then you may need a replacement bracket.
