  3. A guide for homeowners on safe, non-destructive methods for 'abandoning' stuck wires and installing new cables in tight conduits without damaging existing infrastructure.
  4. A specialized, low-friction, high-tensile strength pull-line kit designed specifically for narrow 16mm corrugated residential conduits.
