The Monarch Tray Lid™ fits perfectly into the top of all sizes of Monarch Trays™. The translucent material means that you can easily identify the contents of the trays, but also that the lid matches all tray colours. Being made from Polypropylene means that the lids are as tough as the trays and that they can handle anything a classroom environment needs. Trays with lids on can be stacked and locked into place. Having a lid on will make moving your trays around easier, without the risk of contents falling out. Dimension: 393.7 x 218.6 x 11mm. Supplied with 5 year manufacturer's guarantee. Fully recyclable and made in the UK.
