The Qompact roll shutter by QMI Security Solutions is the evolution of roller shutter design. The unique, proprietary design features a special slat design that rolls into a tighter coil, reducing the shutter box size by up to 40+%. The curtain is divided into groups of different sized slats. As the roll gets larger, the slat size is adjusted so that the hinges sit next to each other (adjoining) instead of on top of each other (stacking)-often referred to as a “nested” design.
