This is a holder for 5 locks and is designed to store them in the Gridfinity-system. It is designed to hold either Double-/Single Euro locks or KIK-cylinders. But you can also design further stencils and store other lock types.

Each "basket" is 2x1 wide in the gridfinity system and can hold one stencil, that just snaps into place in one of the slots in the "basket". These can be stacked, but usually the double euro locks are too long for this to make sense. Fits nicely into IKEA Alex drawers.
