Brand NEW! SECURITY LOCK: Lock an empty RJ45 port in a patch panel, wall plate or network switch to prevent accidental or unauthorized connection of a cable. This RJ45 locking insert helps prevent unwanted cables from being connected and maintain strict control over your patch panel, wall plate or network switch?s RJ45 ports. EASY TO USE: Just connect the N2LPLUG-010-YW to the panel or switch?s RJ45 port for a secure lock. You?ll hear a click to confirm the insert has locked into place. To remove the insert, use the Tripp Lite N2LOCK-KEY-RD security key (sold separately). UNIVERSAL DESIGN: This RJ45 lock insert works with most panels, wall plates and switches with RJ45 Ethernet connectors. The yellow color-coding allows easy, fast identification in a crowded rack or patch panel and helps prevent the insert from becoming inadvertently removed. The intsert's compact design doesn?t interfere with adjacent RJ45 Ethernet jacks, even in high-density applications. - All international buyers are responsible for all tax, duties and/or customs fees.
