The LEGRAND 3' CAT5E SNAGLESS PATCH CABLEBLUE, part number 10015526, is an Ethernet cable designed for network connectivity. The snagless design helps prevent damage to the RJ-45 connector tab during installation and removal, which can be beneficial in high-density cabling scenarios or when making frequent changes. As a CAT5E cable, it supports common Ethernet standards, making it a practical component for extending or establishing network links where a 3-foot length is appropriate.
