The Ultimate Multi-Slide Door is more than just a panoramic door, it’s a gateway to indoor-outdoor living with performance that stands up to any weather, coast to coast. Design your ideal view, with sliding panels available in configurations that move in one direction or part in the center, and panels that stack in full view within the frame or conceal within a wall pocket. When accessibility is important, choose an optional low-profile sill that maintains a smooth, flush transition from indoors to out. In sizes as big as 56 feet wide or small enough to create a counter-height, kitchen pass-through option for a patio or deck, this door opens possibilities. Features: Choose from 22 operating configurations; Individual panel sizes available up to 6 feet wide by over 11 feet high; Performance and high-performance sill available, along with a low-profile, flush universal design sill for accessibility; Available with IZ3 coastal/hurricane certification; CE certified.
