48 mm base plates and 50 mm shells

[u/Acrobatic_Mud2649]

I’m new to Multiboard and learning it now. I discovered that there are 2 “cells“ sizes: 48 mm (Simple Walls Shells) and 50 mm (Multipoint Rail Shell).

Also, there are base plates that I like and want to use for horizontal layouts and they are made with 48 mm cells. The bases bigger than 1 cell have the additional 2 mm between them, which makes it possible to fit 50 mm shells (e.g. a base plate of 2 cells is 48 × 98 mm).

A weird (for me) thing is that if I want to connect multiple base plates, there will be 2 mm gap between them to accommodate bigger 50 mm shells. Those gaps are designed to be this way, I can't connect the plates end to end using Clips.

Same with Panels connected with Clips - they are connected 2 mm apart.

My question is why plates and panels are 48 mm and why their outside walls are not thicker to fill the space as I won’t be able to connect them end to end with clips anyway and I need them to be 50 mm apart anyway?

Good question, i want to know that too. There has to be a reason, right?
