Particular attention must be paid to the wheelchair, as it is considered to be part of the player. Contravention of the following rules will result in the wheelchair being banned from the game. A protective horizontal bar at the front/side of the wheelchair must be 11 cm from the floor at its most forward point and throughout its whole length. Such a bar may be straight, angled or curved between the two front castors. Where the angle is made up of two or more straight bars joined, the external angle of the joined bars should not be more than 200o degrees. Wheelchairs with the footplate positioned behind a single front castor must have a protective horizontal bar extending to the rear wheels in advance of the castor.
