Tripp Lite Universal RJ45 Locking Inserts, Yellow, 10 Pack - Cable Removal Lock - Yellow (pack Of 10) - N2LPLUG-010-YW

The N2LPLUG-010-YW lets you maintain strict control over your patch panel, wall plate or network switch's RJ45 ports. The insert locks into an RJ45 port, preventing those without proper access from connecting cables. Not only does this protect data and deter tampering, but it also helps prevent a network connection from weakening due to too many ports in service. This package includes 10 yellow RJ45 locking inserts.
This RJ45 insert secures a lock to most types of RJ45 jacks in a patch panel, wall plate or switch to prevent unauthorized connection of a patch cord or other compatible network equipment. 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).
Yellow color-coding allows easy, fast identification in a crowded rack or patch panel and helps prevent the insert from becoming inadvertently removed. The insert's compact design doesn't interfere with adjacent RJ45 jacks, even in high-density applications.
