I really like the product. And I understand that the presence of studs is important. However, the placement of the bolts ended up right in front of the terminals I had to use. enough 2 AWG terminals for my build. (Busbars from the original midnight solar shunt could not be mounted on a Victron 500a shunt.) Tinned copper. Excellent stuff. Works well. The only annoying thing is that the only two 2 AWG terminals on the bus are blocked by the connection bolts (posts). There is nothing that cannot be repaired with a saw and angle grinder.
