Procom 8 Core Burglar Alarm Cable Wire White PVC. This is only a part roll, marked up as 57m remaining. This is one of several part rolls left over when a new burglar alarm system was installed. The bobbin has been wrapped in cling film to help prevent it unrolling all-over. The first few meters may have marks and scuffs on the outer sheath as it was taken off the reel to be cut to length.
