Coaching Box

[ref18]

At my last association meeting, we spent a lot of time covering the coaching box, the application of the coaches rule, etc.

I'm just have a few questions about how other associations deal with it.

How many associations use the coaching box??

And

Are there floor markings to designate this box, or do you explain to the coach before the game what area is covered by the box, or is the coach expected to know where he can and can't stand?

Do you use the 28'line, to 14' line, or can the coach walk the whole length of his bench, or from the 28' line to the endline?

This question only applies to Fed rules, because i'm pretty sure that in the NCAA, the coach can walk from the 28' line down to the endline.
