High security: these pliers are made of insulating modified nylon 6.6 and tinned copper for high flammability and high conductivity. They are waterproof, resistant to corrosion and aging. Reliable connection: thanks to the spring-clamping technology, the clamping force of the connectors can be automatically adapted to the thickness of the wire, which makes the wire connections resistant to vibrations and maintenance-free. Easy to use: no tools required. Just lift the lever 90, put the wire in and push the lever back down. It greatly facilitates your work. Each clamp has a test opening which facilitates thetesting and waiting. Universal connectors: they are suitable for solid and twisted conductors from 0.08 to 2.5 mm2 and flexible conductors from 0.08 to 4 mm2. Ideal for lighting systems, building wiring, communication systems and warning systemssafety.
