A system has a surface intended to separate two chambers within the system. The surface has an aperture for allowing passage of at least one communication conduit. A shroud is positioned on the surface at the aperture, and has at least two portions defining a central opening to allow the communication conduit to pass through the aperture and shroud. The two portions of shroud have mating clamp ears in contact with each other. Securement members tighten the clamp ears against each other to provide a seal at an end of the shroud remote from the surface.

The system as set forth in claim 1, wherein there are two mating halves of said shroud which are secured together. 7. The system as set forth in claim 1, wherein a fiberglass tape is wrapped around said at least one communication conduit at the location of said mating clamp ears. 8. The system as set forth in claim 1, wherein said shroud includes a plurality of openings at said end, and there being outer ends to said at least two portions of said shroud with said mating clamp ears at said outer ends, and said plurality of openings including at least one outer opening positioned adjacent each of said mating clamp ears at said outer ends, and at least one intermediate opening intermediate said at least one outer opening, with clamp surfaces provided between said at least one outer opening and said at least one intermediate opening, and there being third securement members tightening said clamp surfaces to also provide a seal at said intermediate opening. 9. A gas turbine engine comprising: a compressor, a combustor, a turbine, and a firewall separating a first chamber housing at least one of said compressor, combustor and turbine from a chamber housing a controller for the gas turbine engine, said firewall having an aperture for allowing passage of at least one communication conduit; anda shroud positioned on said firewall at said aperture, said shroud having at least two portions defining a central opening to allow said at least one communication conduit to pass through said aperture and said shroud, and said at least two portions of said shroud having mating clamp ears in contact with each other, said mating clamp ears comprising two sets of mating clamp ears positioned on opposed sides of said central opening, including first securement members to tighten said clamp ears against each other to provide a seal at an end of said shroud remote from said firewall;said shroud has a platform base receiving second securement members to secure said shroud to said firewall; andsaid platform base includes a full cylindrical portion formed on one of said two portions of said shroud, and a second portion smaller than said full cylindrical portion formed on another of said at least two portions of said shroud. 10. The engine as set forth in claim 9, wherein there are two mating halves of said shroud which are secured together. 11. The engine as set forth in claim 9, wherein a fiberglass tape is wrapped around said at least one communication conduit at the location of said mating clamp ears. 12. The engine as set forth in claim 9, wherein said at least one communication conduit is an electric wire, and a grounding element is received within at least one of said at least two portions of said shroud, and said grounding element for electrically grounding said electric wire. 13. The engine as set forth in claim 9, wherein said shroud includes a plurality of openings at said end, and there being outer ends to said at least two portions of said shroud with said mating clamp ears at said outer ends, and said plurality of openings including at least one outer opening positioned adjacent each of said mating clamp ears at each of said outer ends, and at least one intermediate opening intermediate said at least one outer opening, with clamp surfaces provided between said at least one outer opening and said at least one intermediate opening, and there being third securement members tightening said clamp surfaces to also provide a seal at said intermediate opening.
