HOZAN Pass Clip - Prevents Incorrect Connections - Reduces Time for Electrician Exam - Pack of 10 with Holder A popular and helpful tool for electrical work practice. This is an auxiliary tool for temporarily connecting wires. You can connect and check multiple wires before crimping. It holds the ends of the wire insulation in alignment, resulting in clean ring sleeve crimping. Even those unfamiliar with the process can work quickly, reliably, and neatly. I was able to successfully pass the electrician exam by using this, so please consider it! #HOZAN #HOZAN #Electrician #Clip #PreventsIncorrectConnections
