Here is the 200x50 front caster wheel assembly for the Golden Technologies Alante (GP201SS/GP201CC) and Alante HD power chairs. Please note that this caster assembly only fits the GP201 and GP202 versions of the Alante series.
It is not the same as the 7-3/4" caster that is found on the Alante Jr. It will, however work on the Alero.
