The armrest release handle for Invacare AVIVA FX, Pronto M91, and Pronto M94 power chairs with Van Seating allows you to adjust the width between the armrests. This threaded lever fits into the lower armrest bracket weldment and snugly secures the horizontal sliding portion of the armrest assembly.

Note: This handle is only for adjusting the armrest width on chairs with van seating. The threads are not long enough to allow it to be used as the armrest height adjustment knob. You will need the Armrest Adjustment Knob for Invacare Pronto Power Chairs to adjust your armrest height.
