Special comprehensive fittings allow these plugs to work with shielded or un-shielded cable. A compression nut establishes 10lb of cable strain relief establishing robust cable strength. Internal conductive compression is used to inter-operate with the cable braid to form a 360° ground plane and is comprehensively shielded. Available in Category 5e or Category 6 versions and with or without dust caps. Category 5e versions do not come with an RJ45 but Category 6 versions do. Bulk cable is sold separately.
