Height of Fence

Hi,
I’m trying to find out the height of the Fence (distance in mm from the playing surface to top of fence) in the IQ Challenge. I can’t find it in the Field Appendix. Just to avoid confusion, I know the height of the perimeter wall. Thanks. Mike

Here’s what the VIQC Bank Shot Game Manual has to say:

Thus the fence is 5" or 127 mm high.
