I bought this to mount into the doghouse of a Pro2c to make the hookups neater. It has holes that you can screw through on each of the three 'free' sides, aswell as two m10 bolt threads for more traditional mounting. For me though two small wood screws will do the trick!
The five outputs allow me to have the two power supplies always connected through, with a third dedicated to the side rack, fourth to the Shout box, and a spare which can be easily adapted to a 4-way 13 amp for any other foh needs.
The connectors aren't neutrik which is a shame, but at this price you cant really complain, and the connectors seem to be high enough quality regardless.
Very solid folded sheet metal design makes it both robust, and gives it a decent 'heft' which would be desirable if using it for a floor package for example.
