This is a really good portable 6U rack case for transporting your amps/patch bays/power supplies/EQs . . . . whatever you need that can be mounted in a rack. It's 13 inches tall, 24 inches wide, and 21 inches deep.
I used this for about 7 years while playing live gigs, and it was really handy. It's completely functional - the wheels roll true and even, the handle extends and tucks away with no issues, and the latches work just like they should. It does have some road wear, as is evident in the photos (it's missing one of the rubber corner feet on the bottom), but it's still nice and solid.
The front has the proper rack mounting points, and I have included enough cage nuts and screws to mount three units. The back has an easy access port which opens with two quarter-turn levers.
This is NOT water/weather proof! SKB sacrificed the sealing/latching rear lid, and used the easy access cover in order to make as much of the internal space as usable as possible, so the typical rear rack rails and sealing lid were omitted.
