Very good condition pop-up rack, new butterfly latches. SKB 12U Rack Case for Mixers.
The pictures do tell most of the story. A Mackie 1600 series mixer (not included) lived in this case. The "POP UP" rack can hold up to 12 rack units of height. A "rack unit" is 1.75 inches.The depth is limited to about 5 3/8 deep. The cover is good for 2 1/2 of knobs, sliders, and levers.
If you just want a rugged case to hold tools, wires, and small accessories, then there is plenty of space. Interior dimensions, assuming using the "rack" mount: 19" wide, 20 1/2" tall, 5 3/8 deep. Exterior dimensions, with cover attached: 24" x 26" x 9 1/2.
Note that the "feet" on each corner extends each dimension by almost 2 inches. The nature of a molded plastic case is that it will absorb most blows without cracking or pressing on the electronics held inside.
