High Safety: These clamps are made of insulating modified nylon 6.6 and tinned copper for high flammability and high conductivity. They are waterproof, corrosion-resistant, and aging-resistant. Reliable Connection: Thanks to spring-loaded clamping technology, the clamping force of the connectors can be automatically adapted to the wire thickness, making wire connections vibration-resistant and maintenance-free. Easy to Use: No tools are required. Simply lift the lever 90, insert the wire, and push the lever back down. It makes your work much easier. Each clamp has a test opening that makes testing and waiting easier. Universal Connectors: They are suitable for solid and stranded conductors from 0.08 to 2.5 mm and flexible conductors from 0.08 to 4 mm. Ideal for lighting systems, building wiring, communication systems, and security alert systems. Large selection: There are a total of 60 reusable connection terminals: 20 x 2 terminals, 30 x 3 terminals, 10 x 5 terminals. All in one box. Easy to carry and inexpensive.Welcome to meet
