Tampões cegos RJ45 EFB, preto, pack de 100

Network administrators in data centres and office buildings know that unused RJ45 ports on switches, routers, patch panels, and wall outlets are magnets for dust, dirt, and moisture.

This bulk pack contains 100 black plugs, enough to cover every unused port in your facility.
