The Odyssey Innovative Designs Flight Zone 8 RU Space Shock Mount Case with Wheels is a heavy-duty case that's designed to transport and protect amplifiers and delicate rackmount gear. The 3/8" laminated plywood contains a high-density EVA foam interior to protect your gear from bumps and shock during transport. This case features front and rear rack rails, 8 RU of vertical rack space, heavy-duty recessed chrome-plated steel hardware and four spring-loaded handles. Two 3" thick front and rear lids provide rapid access to the contents. Mobility is expedited by four 3.5" swivel casters (two locking) that need to be assembled.
