Is this a fail ? Or is this acceptable

[Eddie702]

I would use another mini in place of the 1 hole but some may not accept that.

An "L" bracket no one can argue with, either with two minis or two strut clamps with a piece of strut bolted to the L bracket.

Two minis are the best, but the one turned over would meet minimum, esp if the better snap ones.

Personally, I would been inclined to the LBs under the other box. Straight runs no bends.
