SAFE - This kit includes 100 PCS, PCT-212 * 40 PCS (2 ports), PCT-213 * 50 PCS (3 ports), PCT-215 * 10 PCS (5 ports). Selection of the best insulating material PA66 modified nylon flame retardant, which has a long service life, no corrosion, anti-agingand 4KV pressure and against electric shock. EASY TO USE - First remove the metal sheath (9~10mm), slightly push the orange clip up 90, insert the cable and turn off the switch. Instead of traditional electrical tape and interwoven butt connectors,technological innovation reduces wiring time by 70%.

WIDE USE - Universal Connectors: They are suitable for 0.08-4mm/28-12AWG solid wire and 0.08-2.5mm/28-14AWG flexible wire. It is widely used in building wiring where space is limited for allconnections requiring. REUSABLE - Each connection terminal has a sensor connection and can also be recycled. Each junction independent shrapnel, different wire managed separately, different diameter can be safety connected. There is a test holein each connector surface, electrical test can be performed without removing the tape, intuitive and easy. Tip: only one cable of the same type can be inserted into each terminal.
