Steel Connections: vertical and horizontal "play"

Steel Connections: vertical and horizontal "play"

Steel Connections: vertical and horizontal "play"

(OP)
I am having a little bit of trouble developing a sense/strategy for where and when steel connections need vertical or horizontal slotted holes for adjustment in the field.... e.g. a steel brick hanger bolted/hung from a gussett plate from a beam above (vertical slotted hole in gussett??) and the brick angle (horizontal slotted hole?) which the hanger supports...

I know it's kind of a vague question and I have trouble articulating what I mean, but anything helps...thanks guys!!
