The pack of 25 black 5.5mm RJ-45 Colored Boots from Platinum Tools help you organize your cables and protect RJ-45 plugs with snagless large Cat6 boots. These 5.5mm (maximum cable OD) boots help you protect connectors and prevent them from becoming tangled messes. Additionally, they eliminate broken release or locking tabs and help maintain radius bend. The RJ-45 connectors are color coded and made of ABS plastic. They relieve stress on cables and also cover the external ground on shielded connectors. The RJ-45 boots work on all Platinum Tools' standard RJ-45 and EZ-RJ-45 connectors.
