Kauden – XT486 RJ45 Dual Plug Type Crimping Tool. As well as the standard RJ45 plug this tool also allows one to crimp the new type of RJ45 plug as used on outsized CAT6A and CAT7 Cables. This tool works on these plugs by moving the tool from standard plug to CAT6A/ CAT7 setting and so removing the steel pin that pushes down on the standard RJ45 plug cable clamp (use positive screwdriver for adjusting screw).
