27"H AV Cart - Two Shelves. At 27" high, this utility cart is designed for transporting heavy audio/visual equipment. Its sturdy construction holds up to 400 lbs. on two flat shelves while the four 4" full-swivel casters (two with locking brake) make the cart easy to maneuver. An ergonomic push handle molded into the top shelf provides greater control and the .25" retaining lip on each shelf keeps contents from sliding off. The cart is incredibly durable with the shelves and legs being made of molded plastic that won't scratch, dent, rust or stain.
