We offer these yellow lids with hinges and locks for the yellow stacking boxes: Each of the stacking boxes has four identical openings on the long sides of the upper edge. The lid hangs in the openings on one side, and the openings on the opposite side grip the lid snap closures.

If you would like to combine yellow boxes with gray lids, you can do that as well. You can also find the gray lids in our web shop. In grey, we offer a cover variant that can only be laid on to close (no hinge and lock). Of course, the stackable boxes can always be stacked with the lid.
