Hi Joe, Height of guarding should typically also consider the distance from the hazard and whether a person could reach over the guarding. There are some nice guidance tables for this in the standards. I'd then add that B11.19 defines guarding under 55" in height as the whole body access as it would be possible to step /climb over this.

In the US and most of the world it is 7 inches maximum from the standing adjacent surface to the bottom of the perimeter guarding and 55 inches minimum from the standing adjacent surface to the top of the perimeter. The top may be required to be substantially higher dependent on how high the robot goes with product in it's EAOT. In Canada the maximum dimension is 6 inches and the minimum height is 72 inches. If you follow the Canadian dimensions for your perimeter guarding iy will be goo for any place you may sell a system.
