The Callero Treble is a really lightweight, multi-purpose tray trolley system that can be easily and safely moved around the learning space with one hand. The handles are high enough not to require bending down in order to push it and it has no sharp edges or angles for extra safety around children.

Lesson time can be maximised with the swift access to trays of pre-prepared resources housed by the Callero trolley, which can be transported effortlessly and with stability due to the large castors. Additionally, the top surface of the trolley can be used to effectively model activities or display resources anywhere in the learning space, ensuring all get a front row view when it really matters.

As is expected of Gratnells tray storage solutions, the Callero Treble maximises storage space on a small footprint, providing 33% more storage space than our standard trolleys to suit end-user requirements. All of these features combined mean that the Callero Treble is more than just classroom storage. It is providing a flexible solution to many challenges commonly experienced in the learning environment.
