Abstract: Curtain grommets that can be easily installed on curtain rods are described. Each grommet includes a front split ring and a rear split ring forming a grommet split at the top that is aligned with a split or gap in the curtain at or above the grommet. Each split grommet is sufficiently flexible to allow the grommet to be installed on the rod without the necessity of stringing the grommets from the end of the rod or removing the rod from its mounting brackets. A liner hook may be attached to the bottom of the split grommet, for example, on the rear ring, and may be rotatable from an extended position for supporting a curtain liner to a flattened or stowed position for packaging, storage and transportation.
