Part of the ultra-flexible Callero range, the Callero Tilted Tray Trolley takes the multi-bin concept a step further with tilt-position crossbars for enhanced visibility and easier access to the bins' contents, making this trolley ideal for classrooms where independent and collaborative learning is encouraged. Anyone of any age should be able to quickly find what they're looking for. Durable steel frame is enclosed on the sides, and both the frame and panels feature a tough, powder-coat finish. Ergonomic handles and included casters (two locking) make it easy to maneuver the cart either down the hall or fully across campus. Completely free of sharp corners and edges, these trolleys are ideal for students of all ages, from Pre-K through adult learning, but they're particularly well-suited to primary education environments. Tilt Tray Trolleys also integrate seamlessly with all Callero and Callero Plus systems. Set 01: 9 F2 Deep Bins.
