100m Reel Black 4 Core x 2.5mm Duct Grade Speaker Cable with Water Blocking Tape
Engineered for direct burial or pulling through ducting/conduit these Duct Grade speaker cables feature a double jacket water blocking tape and a waterproof moisture and UV resistant polyethylene sheath.
Using new production techniques they feature a dry water blocking fleece tape that’s wrapped around the core bundle. It only becomes active if moisture comes into contact with the tape which then causes it to swell to form a blocking layer of gel. This immediately stops moisture migrating through cables and enables the equipment that they’re connecting to function without interruption.
