I got a 2 gang surface mount back box the other day that had cable grips
in it, which I thought was a good idea.

But it only had two, and they weren't opposite but one on the side and
the other top (or bottom).
Has anyone any idea why this would be? Why not fit them on all four sides?

For a cooker switch with an outlet cable, probably. Cable grips take up space, and cost the manufacturer money, so they don't fit four. Only one will be likely to be required.

You could get a back box with conduit knock-outs, and fit cable glands.

Ah, makes sense. Cheers.

Oddly, I ventured into my 'loft stock' (bits bought and not used) the
other day for a back box (single) and found a new one which also had a
cable grip. I don't recall buying it, nor was the bag market as having a
grip etc and I don't recall seeing one before. Grips on the rear of a
face plate for fused/switched flex outlets yes but not on the back box.
