A grommet like device including at least three layers that can be attached to a larger flat surface to allow a cable or other object to move perpendicularly through a hole in a movable fee floating layer of this grommet like device, such that the cable or moving object can displace a freely movable portion of the grommet further in a direction largely parallel to the surface to which the grommet is attached, than a small opening or attachment in the center of the grommet, would otherwise allow without causing a lateral movement of the larger surface, substantial pressure or friction, or a larger unobstructed opening in the larger flat surface. |
