A device for receiving and organizing twisted pairs of conductors from a cable having a plurality of twisted pairs of conductors includes a block with upper and lower surfaces, first and second opposing end walls that define a longitudinal axis, and first and second opposing side walls. The block further comprises at least one aperture extending from the upper surface toward the lower surface, the aperture being sized and configured to receive each of the plurality of twisted pairs of a cable. Each of the side walls includes at least one open-ended slot opening downwardly, each of the slots being sized and configured to receive a respective twisted pair of conductors. In this configuration, the device can facilitate termination of twisted pair conductors onto IDCs or the like and can provide a termination with less dimensional variation (and, in turn, less variation in electrical performance) than prior termination devices.
