Feature: 1. Made of metal galvanized material, which is waterproof and anti‑corrosion, and can be used in various environments. 2. The overall high‑temperature quenching process of the paralleler has high hardness and good wear resistance, and has a large load‑bearing torsion. 3. With outer loop fixing and inner bevel cut, the five‑hole clamp is not easy to loose and not messy. 4. After clamping all the wires, they can be wound easily, and the wires are tightly wound and not easily broken. 5. The doubling device is usually used with an electric drill, and is suitable for electrician maintenance and assembly, wire doubling processing, and metal wire doubling. Specification: Item Type: Wire Twisting Tools Material: Stainless steel galvanized Style: Electric How to Use: 1. Wire rehearsal and neat jacks (one wire must be inserted into the No. 1 hole, and the rest are discharged at will) 2. The pliers must clamp all the wires (not tightly clamped may cause no peeling and disconnection). The wires must be lined up and clamped on the pliers (four wires must be used with needle-nose pliers) 3. 5pcs 2.5 square or 2pcs 4 square drill torsion is about 8-10, 3pcs 4 square drill torsion is about 12-15 4. Only one wire can be inserted into each inlet hole. Package List: 2 x Wire Twisting Tools Note: The electric model needs to be used with an electric drill. The vise should be tightly clamped against the wire doubling device, and three or more wires need to use an electric drill above 16V. The torsion of 5pcs 2.5 square and 2pcs 4 square drills is about 8‑10, and the torsion of 3pcs 4 square drills is 12 ‑15 or so.
