34" H AV Cart - 3 Shelf, Cab, Front Pullout. This multipurpose cart offers three 1.5"-thick shelves to reliably support AV equipment, a retractable tray for keyboards or laptops, and a 20-gauge steel locking cabinet for storing equipment. Durable shelves, with a raised texture and .25" retaining lip to secure items during transit, are made from an injection-molded thermoplastic resin that won't scratch, dent, rust or stain. Square legs provide strong structural support; 4" full-swivel casters roll easily across a variety of surfaces while two locking brakes allow quick stabilization.
