What's the use of threading panel?

Convenient threading. The threading panel is an auxiliary tool, which is mainly used to facilitate users to thread. Threading is to thread a steel wire with good elasticity into the catheter first, which is used to pull the wire and also plays the role of checking and dredging the catheter. Because the wire is soft, it can't go a long distance. In order to save costs, some construction units bring steel wires into nylon ropes for quick threading.
