This modular system consists of drawers and frame elements in three sizes that can be arranged in any combination. Lader can be built to meet your personal needs. The optics of the system can be changed by turning around the drawers, which have two different fronts. One front has a single finger hole, the other has two additional holes for inserting numbered, lettered, or symbol labels. In addition, the upper drawer can be fitted with a lock. Lader can be delivered with wheels or feet as required.
