Abstract: A grommet having a groove that corresponds in size to a hole in a wall, and a boot extending from the grommet in the shape of a nipple which forms an outer wall. The grommet also includes an inner wall that extends radially inwardly in the same plane as the wall to which the grommet is mounted, the inner wall defining an aperture through which the wire or bundle of wires passes. The outer wall and inner wall define a chamber for collecting water that enters the inside of the boot. The outer wall further defines a slot through which the collected water drains to remove the water from the inside of the boot.
