A method is provided for making a closure housing for sealing. The method includes forming a plurality of housings. At least one of the housings is formed as a concave housing with an open face. The method also includes aligning one or more layers, such as for example an elastomeric film or conformable selant, on one or more of the concave housings in a substantially planar configuration across a circumferential perimeter of the open face of each of the concave housings. The method also includes securing the elastomeric films on the circumferential perimeter of the open face of each of the concave housings. The elastomeric films are adapted to interface one or more cables when the cables are interposed between the elastomeric films on the housings.
