The Ideal 85-383 RJ45 RJ-45 Snagless Strain Relief Boots, Blue, 6.5mm, CAT6, Pack of 25 can be used when a new patch cable is being made. The boots need to be placed onto the cable before both connector ends are terminated. The Ideal 85-383 boots help to protect the modular plug body, especially the latch tab, from external handling damage. The strain relief feature on the boots helps to maintain the cable bend radius and limits conductor movement inside of the connector that can lead to continuity failures over time. This unit fits industry standard RJ45 8P8C connectors. Users are provided with a tool that features a 6.5mm diameter cable opening. The Ideal 85-383 is designed for CAT6 and CAT6A twisted pair cables with jacket diameters of 6.0mm - 7.0mm.
