ncludes 15 each of RJ-45 Cat 5e and blue snagless strain relief bootGreat for making professional performing and looking custom length cables8 position, 8 contact RJ-45 modular plug for Cat 5e, 100O balanced twisted pair 100 MHz cables50 micro-inch gold plating on contact mating area for long term reliability in connectivity, even after hundreds of mating cyclesBoots prevent broken connector tabs and snagging while extending connector lifeStrain relief boots 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 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.Prevents broken connector tabs and snagging while extending connector lifeMinimizes cable bends that can reduce data speed and result in data lossDampens cable movement and vibrations that can result in premature connector failureSized for Cat 5e and smaller diameter Cat 6 twisted pair cablesFits industry standard RJ-45 8P8C connectors5.5mm diameter cable opening
