Welcome to our store! Optimal performance Unshielded transparent contacts reduce the distance between wire loops and contacts. They ensure a solid connection for the best performance that suppresses frequency noise. Easy to identify cable order The through-hole function allows cables to pass through the contact entirely so you can check that they are in the correct order before crimping. Category 6 compatibility certified for a Gigabit Ethernet-compatible network. These gold-plated contacts are compatible with both solid and stranded cables. They work with all types of keystone outlets and RJ45 keystone inline connectors, and support 24 to 26 AWG round or flat network cables. CAT6 23awg is only supported for solid cables. Easy to crimp even though it works for most types and models of RJ45 crimping tools. Recommended to use a dedicated through-hole crimping tool. Satisfaction: Our customers are our highest priority.
