DETERMINING COMPATIBILITY
Wheelchair Types
The J3 Back is designed to be compatible with most
wheelchairs with the following exceptions:
Wheelchairs that are angularly adjustable, recline or tilt and
result in a back angle greater than 60 degrees from the
vertical should not be used.
WARNING
Use with these types of wheelchairs may cause the
back to accidentally disconnect from the wheelchair
resulting in a fall and the potential for serious injury.
Wheelchair Dimensions
The J3 Back is designed to replace the wheelchair's sling
upholstery. Prior to installation determine if the wheelchair
used has compatible back canes, by measuring the width
between your back canes as seen in Figure 1. Then using
that measurement, check Table 1 to determine if the back
will fit your chair.
Next check that the back canes are a compatible diameter.
The J3 back hardware can be mounted on wheelchair
back canes ranging from 3/4" (1.9 cm) to 1 1/8" (2.85 cm).
Measure your back cane diameter (Fig. 2) and refer to Table
2 to ensure your back canes are compatible.
If you cannot determine that the back canes are compatible
please contact your authorised Sunrise Medical provider
or Sunrise Medical customer service.
