The Request Close Fill icon shows two pairs of rounded blocks: the left pair is connected by a vertical stem, while the right pair has an X above the lower block. Drawn in the solid style on a 24px grid, its rounded corners give the filled forms a softer UI presence. Use it for request-close controls, dismiss actions, and cancellation. It belongs to Rounded Fill - Streamline Material set in the Streamline Material family.
