Great portable 4U rack

I was looking at more traditional portable 4U rack cases from SKB and Gator when Jeremy, my sales engineer, pointed out this rack bag. He has personal experience with it on the road and was able to explain in detail how I could fit my rack equipment (power conditioner, wireless mic receiver, and keyboard mixer) into it with room to spare for the various wall warts and cables that need to be contained internally. It's been perfect! I bundled the power and audio cables that go to my various keyboards and now have a portable solution that is rugged enough for our local gigging, easy to move (~33 lbs loaded), and very easy to set up. There's room inside for a pouch with my headset mic, and there's room in the outside compartment for miscellaneous cables and adapters.

Solid but lightweight

The side zipper is big enough to put in your tablet that will allow you to control the soundcraft. Despite being incredibly lightweight it is sturdy enough that you could stack speakers on this case! I'm very happy with this purchase because I don't have to worry about wear and tear on my digital mixer and sometimes I carry it by the handles and sometimes I strap it across my shoulder and use my now freed up hands to carry whatever I want.

Gator 4U Rack Bag

Just what I needed. I really didn't want the depth of this rack for my MR18 Rackmount Mixer, but thankfully it is deep enough for me to stow my external router behind the mixer. It works well!

Perfect for local gigs

Not much to add from what others mentioned. I was worried about the qaulity of the product till I read previous reviews and agree with them. It's well made, definitely sturdy enough to keep your rack gear safe. Came with screws in the big pocket. Got this mainly for local gigs where I just want to bring in the minimum stuff I would need FoH vs dragging a heavy roadcase that only comes out for touring. Couldn't be happier.

Great protection and portability!

SKB makes great, affordable cases. Perfect fit for the Behringer cX32 Rack with a 2 space power conditioner.
