"I won't sell it if I won't use it!!" - Alan, Owner of SpeakersForMusic. Seriously. New, unused item from US distributor.10 space (17.5 inches of rackable space, 10 x 1.75") Front and Rear rack railsStandard 19 inch wide mountingRack Depth without lids: 16.5 inchesSteel butterfly style twist latchesNEW! Storage Pouch screen-type with zipper, built into rear lid ABS & Aluminum, lightweightRubber gasket in lids to seal against dirt and spills StackableWith Lids: 22.5 inches deep, 22.5 inches wideShipping box is 23 x 23 x 21.5 inchesShipping weight (in box) is 22 pounds. What's a "U"? It stands for Unit or Rack Unit which is standardized at 1.75 inches tall Here is a reasonably priced molded ABS & Aluminum lightweight 10 space (17.5 inches of vertical rackable space) amp or effects rack, kind of generic but with an obscure name on it. The case shell without lids is a medium depth of 16.5 inches, in line with modern amps and shallow enough to use as an effects rack. This rack has Front and Rear Rails with replaceable steel threaded strips for mounting your rack equipment; screws and washers included for your convenience. Butterfly steel twist latches. Stack-able. Good protection for your equipment. Zippered storage area in one lid. NOTE: If you load enough equipment into this rack to require 2 people to move it, the handle design is not as nice as current SKB and Gator ABS racks. It's like the older SKB racks and if you put your hand in the handle palm down, the top of your hand will tend to press into the top of the handle assembly and cause significant Pain! I am telling potential customers about this issue because of my experience with it. The other racks with better ergonomics cost a lot more!
