The CAT6A STP RJ45 Shielded Modular Plug comes with a polycarbonate-wire aligner and load bar that allows for consistent twisted-pair seating during plug assembly on high-speed networking and computing applications for optimal performance. Gold plated connectors on these RJ45 connectors guarantee best possible transmission speeds for lightning fast internet connections. In order to crimp these plugs, a crimper with removable presser bar is required, otherwise part of the plug will be crushed.
