The items inside the clear bags are RJ45 strain relief boots (also commonly known as ethernet connector plug caps or covers).Key FunctionsSnag Protection: They feature a special molded hood or bump design that covers the fragile plastic locking clip of an RJ45 connector. This prevents the tab from snagging, bending, or snapping off when pulling cables through crowded network racks, walls, or conduits.Strain Relief: They prevent the ethernet cable from bending too sharply at the connector base, reducing structural stress on the copper wire terminations and extending the overall lifespan of the patch cable.Environmental Protection: They safeguard the connector back from dust accumulation, debris, and oxidation
