    The ANSI A117.1 states that reach is 15"-48". IMO, 48" to the center is the highest permitted.

    Trying to figure it out. We we're told it was 42 to center?

    42" is fine, but its not the highest you can install.

    These may help.





    Figure 5b
    Maximum Forward Reach over an Obstruction
    The maximum level forward reach over an obstruction with knee space below is 25 inches (635 mm). When the obstruction is less than 20 inches (510 mm) deep, the maximum high forward reach is 48 inches (1220 mm). When the obstruction projects 20 to 25 inches (510 mm to 635 mm), the maximum high forward reach is 44 inches (1120 mm). (4.2.5, 4.25.3).



    Figure 6(b)
    High and Low - Side Reach Limits

    The 30 by 48 inch wheelchair clear floor space is located a maximum 10 inches (255 mm) from the wall.



    Figure 6(c)
    Maximum Side Reach over Obstruction
    If the depth of the obstruction is 24 inches (610 mm) and the maximum height of the obstruction is 34 inches (865 mm), the maximum high side reach over the obstruction is 46 inches (1170).
