Tower Dimensions

[Kpchem]

Hello. While brainstorming with my team, I came across what seems to be a contradiction in regards to the dimensions of the tower. If you look in 6.2.4, it states that

The PLATFORM is 44 inches wide by 36 inches deep

I took this to mean that the tower also holds these dimensions for length and width.

However, if you look at the detailed field drawing, specifically GE-10028, it shows that the top of the tower, which extends vertically from the corners of the platform, forms a square.

Furthermore, in 6.2.4 it states that the tunnel is 36 inches wide, which would imply that the bars of the tower are also 36 inches apart. And if you look at the GE-10047 in the detailed field drawings, it shows on the second page that the bump is 36 inches wide, which means that the bars of the tower are 36 inches apart in that direction as well. This supports the drawing of the top of the tower being a square, but it goes against what the manual states, so I am left confused about the true dimensions between the bars. Can anyone help me to clarify this?
