Abstract
A push plug designed to interact with and seal an open end of a length of conduit containing a cable. The plug is comprised of a cap, a neck, and a body. The body contains a number of saw-toothed annular ridges. The plug is manufactured from an elastomeric material which allows the plug to be inserted into a conduit opening of a diameter smaller than the diameter of the saw toothed ridges which creates a frictional seal which resists removal of the plug. The plug body further contains passages running longitudinally through the center of the plug. These passages allow cable run through the conduit to be drawn through the plug and inserted through a thin, flexible membrane covering the plug cap.
