The present disclosure relates to a composite cable seal for use in a telecommunications enclosure. The composite cable seal includes a frame material and a sealing material. The frame material can be configured to control positioning of the sealing material, and to prevent the sealing material from being over-compressed. The sealing material can be configured to provide effective sealing at a cable port and to provide effective sealing with respect to the enclosure (e.g., at a triple point of the enclosure).
