Cable railing is a type of railing system that uses horizontal or vertical cables as infill material, instead of traditional pickets or balusters. In interior spaces, cable railings are often used for staircases, lofts, and balconies to create a sense of openness and visually expand the space. In exterior settings, cable railings can be found on decks and patios to provide unobstructed views of the surrounding landscape while still providing safety and security.
