The Cord Plug End is a plastic 3-prong connector that is quick and easy to attach to our color cord. Made of hard plastic, the plug comes with a screw to open the plug for wiring. In addition to the plug end, we recommend that you also purchase a Barrel Cord Grip, which can be used to secure the connection between the cord and the plug end. Watch the product video for a visual on how to assemble the parts together. With all lighting projects and DIY fixture assembly, we always recommend consulting a licensed electrician.
