Made of a narrow band of spring steel, by careful manipulation, the tape can be guided through confined spaces such as wall cavities or conduits in many countries. The goal is to push toward an area where guide string has been dropped inside the confined space and to pull it through, so the guide string can then be used to pull through various types of wiring, such as phone wire, network cables or speaker wire.
A narrow strip of spring steel tape, manipulated carefully, can navigate tight spaces like wall cavities or conduits in many countries. The aim is to push it towards a location where a guide string has been dropped and then pull the string through, enabling the passage of various types of wiring such as phone wire, network cables, or speaker wire.
