Abstract
Abstract There has been provided a conduit cable seal comprising a clamping means having at least two relatively thin, spaced steel plates having axial holes therethrough for passing a cable and a radial slot extending from an outer end of each of the cable holes to the outer edge of the plates. A fastening means draws one plate close to the other and a resilient sealing member disposed between the plates seals the conduit beyond the cable seal when the fasteners urge the plates toward each other.
