Generally, the plastic corrugated pipe manufacturers is roll with 25 meters, 50 meters or 100 meters long.
How can such a long pipe pass through the wire and cable harness?
A buyer said: I cut it and then feed wire harness inside. This is really a method, but if the wire used is long, it can't be cut into pieces.
B buyers said: feed the wire harness to pipe directly. this is another method,but it may cause blocked in the pipeline.
