Case stay-wires using cheap picture-mounting kit

Now I am starting to colonize my second 20-unit rack box, I worry it might fall flat from the weight of the modules I plan to eventually fill it with. Well, this is almost guaranteed because I already wear it with a guitar strap.

I noticed the extra, undocumented M3 screw holes in the ends of the case units and decided to add some stay-wires to keep things at the right angle.

I found a picture mounting kit at my local hardware store. I cut the wire to fit neatly with a comfortable angle for the second case attached via the hinge kit. I used red heatshrink to cover the rough ends and reinforce the join.
