By the time I was regularly using Kadees (1969-70) the problem had been solved and the Kadee "5

can find
Kadee "5 and 10" boxes from the 1970s and they are different,

slightly, from the current ones.
I assume you are refering to the triangular portion of Kadee's coupler box bottom part that makes it wider at the bottom?
I have always wondered what this feature is good for. I think these couplers have already enough play inside their box. Creating more looks counterintuitive for me.
