Always approach a shunt with caution, from the left side. Avoid direct eye contact and ever so quietly give praise. Then and only then may you attempt to mount. I normally, (unless I'm feeling a little wild) I carefully mount, first one side then the other.
Simple solution. Small piece of wood 90° angle bracketsView attachment 18162
The wires hold it in placeThanks. I’m putting this all in a box though. I’m kinda wary of leaving a naked shunt. I’m thinking maybe small Tupperware and a double sided Velcro.

As an earlier post mentioned, it is not a good idea to mount them in a small enclosed box, they can dissipate a significant amount of heat when passing large currents, you need to allow that heat to dissipate, not box it up. A 500 amp, 75 millivolt shunt will dissipate 37.5 watts of heat running at full capacity (500 x .075). If you boxed that up in that small plastic box, it would likely get hot enough to melt the plastic.Long time ago I came to the conclusion of using Deltec Shunts which have a phenolic backing / mounting which you can screw to a wall or whatever. A Shunt can generate heat and as such should be mounted so that the heat is a non issue (also increases resistance and that's not good).
The ironic thing is, there are Shunt Bases / Holders for sale that cost as much as a complete shunt !
Few idea's on how to make a base:

A good idea here using an ABS Box (could even let the shunt free-float inside one if a cover is on it.

Does it matter if it is a naked shunt?Always approach a shunt with caution, from the left side.
Only durring mating seasonDoes it matter if it is a naked shunt?
I run with Deltec 500A/50mv shunts, they do get "warm" but never HOT. Always derate of course, as mentioned above, by a minimum of 25% at least just to be on the safe side.As an earlier post mentioned, it is not a good idea to mount them in a small enclosed box, they can dissipate a significant amount of heat when passing large currents, you need to allow that heat to dissipate, not box it up.
