BN BB / BN 14 x12 BB

[SuffolkPaul]

Hello all

So I use on my single hive a 14 x 12 BN BB, but also have a Standard BN BB, and i would like to make an EKE which i can fit to my standard box so it will take the 14 x 12 frames. My question is how high should the EKE be?

is it 88.9mm and in 3.5" depth?

Best Paul
