I never claimed to by a physicist or engineer, but I have found myself
trying to think like one in recent days.

By borrowing from numerous sources and integrating a couple ideas of my
own, I drew up a blade guard design and assembly which suits my present
purposes.

It relies however on a short vertical beam being supported ("hung") by a
short supported length of 2by4. The shot vertical beam may consist of a
short length of square steel tubing, a short length of 2by4 material, or
similar.

I would like to be able to MOVE the beam along the length of the 2by4
(for horizontal adjustment). My question is: Is there a familiar
hardware item that will help me with this? All it needs to do is wrap
("hook") around the 2by4 and provide a means to attach what I want. It
seems "definitely related" to a joist hanger, but seems to be something
different. The joist hangers that I have seen do not have "hooks to
wrap around the top of the support" (probably because that would not
evenly distribute the "load" in general).

BTW, I AM striving to be mindful of "torsional" forces.
