10mm 6-Inch 4-Wire Solderless Flexible Coupler for Waterproof 5050 RGB LED Strip Light (10-Pack) These 10mm 4-wire solderless flexible couplers allow you to easily connect two waterproof RGB LED strip lights together with flexible wire between the strips. Cut and reconnect strips with these couplers to perfectly fit contours and corners for a professional look. Open the tops of the connectors, insert the strips, then close the tops and it's done. These are designed specifically for use with waterproof strips that have a silicone coating. Instead of clipping on to the top of the PCB like non-waterproof connectors, these punch through the bottom of the strip to make a secure connection to the PCB without the need to remove any of the silicone coating. Now you can connect waterproof strips quickly and effortlessly without compromising the waterproof nature of the strips. 10mm 4-conductor strips are normally used with RGB color changing strip lights.
