Gratnells Callero Plus Treble Trolley – 24 Shallow Trays

The Gratnells Callero Plus Treble Trolley with 24 Shallow Trays is a lightweight, safe, and highly versatile storage solution designed to keep classrooms and learning environments organised. With three full columns of shallow trays, it offers 33% more capacity than standard trolleys while maintaining a compact footprint.

Built with safety in mind, the trolley features StopSafe runners to prevent trays from being pulled out too far, large castors for smooth and stable movement, and rounded corners with no sharp edges. High handles make it easy to manoeuvre with one hand, without the need to bend down.

The top surface can be used for demonstrations or as a display area, making it more than just a storage unit – it’s a flexible teaching resource that supports independent learning, efficient lesson preparation, and interactive teaching.

Please let us know your preferred tray colours when ordering. If you’d like a mix of colours, just add a note at checkout or contact our team — we’re happy to customise the trays to suit your classroom.
