Connector Type
Check the Wheel Rim type by holding the Compatibility Gauge to the inside of the Wheel as shown
below. Try each of the 3 shapes, type 1, type 2 and type 3, one at a time. The number of the shape
that fits your Wheel Rim (1, 2 or 3) corresponds with the type of Connectors you will need.
Does one of the Connector shapes fit?
YES my Connector number is NO
Wheel Compatibility
Check the packaging to ensure you have the correct Nu Drive for your wheel size.
WARNING! APPLY WHEELCHAIR HANDBRAKE.
Use the Compatibility Gauge to ensure that the wheel hub is the correct width and height to fit your
Nu Drive. If either dimension does not fit then the wheel is incompatible with the Nu Drive system.
N.B. There is NO minimum width or height for the wheel hub and there may be a gap between
the Hub and the Gauge.
My wheel hub IS within
the width and height limit!
My wheel hub IS NOT within
the width or height limit!
