The Insert Center Right 1 icon shows a large rounded square on the right, short horizontal bars on the left, and full-width bars above and below. Drawn in the duotone style on a 14px grid with a 1px stroke, its smooth curves and two-color treatment keep the layout clear and expressive. Use it for insert-position controls, split layouts, content placement, editor toolbars, and responsive interface builders. It belongs to Flex Duo set in the Flex family.
