PRO filing cabinets are a classic solution that guarantees comfort and convenience of use. The standard (binder) height of the shelves can be easily adjusted along the entire height of the furniture, and each shelf has an additional protection against accidental sliding out. The durability and stability of the furniture is guaranteed by the glued construction and a simple leveling mechanism. A numbered lock with a replaceable insert, including various decors and the possibility of using high gloss colors on the fronts, is a response to the individual needs of users.
