Gratnells Callero Trolleys

Callero is an organic storage system that grows as your teaching
needs change.
Our modular wall units let you build up or build across, giving you the smallest
footprint for the largest storage capacity. At Gratnells we have more options than
any other school range and the most flexible solutions for limited spaces. What’s
more, they are sustainable: our recyclable units share a wall, meaning less plastic
and more leftover space.
