ABSTRACT:
A level on a wheelchair allows the cambered rear wheels to be easily adjusted to eliminate toe-in/toe-out. The level comprises a ball encased in a curved track. The curve track is formed in a clear housing that mounts to the underside of a wheelchair camber tube or wheel axle. The camber tube or wheel axle is rotated until the ball aligns with an indicator mark indicating that toe-in/out has been eliminated from the cambered wheels.
