So if the path is, for example, 30 cm., the plate must be 30 cm. large.
Am I correct?
However, considering the ease of installation, it is physically impossible to get a perfect fit, so it might be a little smaller. Also please refer: 2.7.6 All measurements in the rules have a tolerance of ±10%.
In the rule the maximum height is 2 cm., in the scheme is <2cm. What of the two?
This won’t be a practical problem either, given the tolerance.
However, your point is make sense, and it has been corrected in the 2021 rule that is being developed.
