MULTI ZERO is the new locking hook from MACO, which is redefining barrier-free design. 20 mm is not the tolerance limit for barrier-free thresholds – no, at MACO, only zero millimetres will do. It is the absolutely compromise-free flush-fit threshold, with no risk of tripping. Whether it is a child’s trike, walking frame or wheelchair, the new locking hook is the unique technical solution for creating a professional, thresholdless transition, without any obstacles. It is suitable for the high-end private market as well as public buildings, retirement homes, nursery schools, and so on. The clever locking solution engages from the sash into the striker plate in the threshold: not only does the double hook offer extra security for burglary resistance (RC 2), it also connects the sash and threshold to form a unit which meets all water and air-tightness requirements. Zero, zilch, zip, nada, nothing can get in between and nothing protrudes at all. Another multi-talent from MACO!
