Songmics grids for C&C cage?

[Perkypanda]

Hi. I have got some Songmics grids and making my first C&C cage. I want to buy the correx pre cut and scored etc as it’s my first go. I have checked and am pretty sure the base from Kavee is the same as the grids are both the same dimensions but has anyone made a 4x2 cage or knows the correct base size for Songmics grids? Would this one fit?

I used kavee correx with songmics grids, no problems.
