The Rack Drawer Systems are the perfect storage solution for everyone from mobile DJs to touring musicians! Smart, compact and rugged, our Rack Drawer Systems are available in 4 or 5 drawer versions and are great for organizing all of your accessories. The drawers, available in 2U, 3U and 4U sizes glide on extension sliders for smooth action. 3 and 4 U drawers have slotted, removable dividers to allow maximum customization. When you're ready to go, just secure the cover, specially designed to hold the drawers in place, and rock and roll on the beefy 3-1/2" casters. It's the ultimate mobile storage solution!
