The H. Wilson Tuffy Cart is an extremely versatile and durable AV cart. Each thermoplastic resin shelf is injection molded and won't rust, chip, crack or peel. Shelves have a raised texture surface and a small safety retaining lip. The three-outlet electrical assembly is UL-approved and includes a 15-foot cord, cord wrap and three cable management clips. Four full-swivel casters, two with locks, support the black resin legs.
