Hi fezzic, thank you for your input.
The 0.8 meters are from product specifications of gates sold in the mid 80s.
Sold in Europe... I am no expert in products used in the US.
So you say the box you saw was about 20 inch in cross diameter?
That would equal about 0.51 meters. I would have to calculate it but I would guess this would result in about the same result as of Mr. Wilson.
