Squama means fish in Latin. Fish have been a symbol of fortune in the Orient since ancient times. LG Hausys applied the shape of fish to the design of window and door handles. It has embodied, in this design, its hopes of good luck, well-being, and happiness for customers and their families. The handle is bent to one side, resulting in sufficient space between the window frame and handle. This allows the user to more easily grab the handle. A part that serves as a lever was applied to result in 30% less strength required when opening the window. The magnetic force-based changeable cover allows users to reflect their unique tastes with greater detail and convenience. The family look design results in a consistent interior décor style for doors and windows.
