High Safety: These pliers are made of insulating modified nylon 6. 6 and tinned copper for high flammability and high conductivity. They are waterproof, corrosion-resistant and age-resistant. Reliable connection: thanks to the spring-clamping technology, the clamping force of the connectors can be automatically adapted to the thick wire, making wire connections vibration resistant 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 facilitates testing 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 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. Everything is in a box. Easy to wear and inexpensive. With this set of 60 pieces. Connection terminals for all types of ladders allow you to easily connect wires from 0. 08 mm2 to 2. 5 mm2 (4 mm2). The lever allows easy opening and comfortable insertion of the ladder. The clamp is corrosion resistant, aging resistant, leak resistant and provides a vibration resistant and maintenance free connection. They can be used up to an ambient temperature of 85C. Plus, they'reusable. Set includes: Pack of 30 2-pole terminals (2, 1 x 1. 3 x 1. 5 cm). Pack of 20 3-pole terminals (2. 1 x 1. 7 x 1. 5 cm) Pack of 10 5-pole terminals (2. 1 x 2. 7 x 1. 5 cm).
