perfect for my use

I bought this case a part of a package deal for my Soundcraft mixer. It fits perfectly and there is all the room I need for all the XLR cables I use for the show. The side pouch holds my laptop and the large handles make it easy to carry. I highly recommend this case for the Soundcraft unit.

Use for Helix Rack (3ru) with a blanking plate. Perfect and good quality.

Nice Bag, great price!

Simple, great bag at a great price. I purchased new rack screws as well. I was surprised by the quality of this Rack Bag. My super salesman at Sweetwater us Ryan Wildermood ext 3090. Get it from the best music retailer by far via the best salesman at Sweetwater. He has been my rep for many years and many sales. There is no one bette.r After 42 years of purchasing professional music equipment , as soon as I found Ryan, there was nothing to fear regarding new gear. Thank's, Ryan, for another terrific desk!

Gator GRB-4U Soft RAck Case

This is one bag that has it all, well built and nice looking but most importantly very functional. Don't hesitate, buy this bag!

Good stuff

I used to use a big ol' SKB slant top cabinet (which was great for years) but, with my newer setup, I needed something to put certain rackmount pieces into a smaller "housing". This rack bag works perfectly. Sturdy, but not too heavy... access from the front or the back, and an extra pocket to throw a couple of cables into. Bam! Good stuff!
