RJ45 Network Plug Lanberg Cat. 5e FTP (100 pcs) A set of 100 shielded RJ-45 [8P8C] network plugs, Cat. 5e, designed primarily for LAN FTP cables.

Thanks to the use of triple prongs (3prong), Lanberg plugs are compatible with both types of cables: solid and stranded.
Solid wire consists of a single piece of metal wire (used in structural installations).
Stranded wire consists of a bundle of thinner wires (used in patch cords and shorter lengths).
