Review on 🔌 STARELO Electrical Replacement Plug & Connector Set: Yellow Shell, 125V 15A 2Pole 3Wire NEMA 5-15P & 5-15R Industrial Grade 3-Prong Straight Blade Grounding Type – Buy Now! by Josh Garber

Key: The fourth and fifth images show the protrusion/channel that needs to be aligned. Only the green ground screw on part ONE points directly to the duct inside part TWO. If this is a bad key description just look at the photos provided for the product. Country orientation is key. The part with the plastic clip (and two screws) is horizontal when the spare end is placed sideways on a flat surface with the floor in the highest position. In this position, the screw holes line up. Of course, this horizontal clamp can be rotated by 180° when the floor is raised. but then the 3 screws don't match the 3 holes. Bottom, clamp horizontally if you aligned 3 screws with 3 holes. You are good to collect it. Alternately? Before disassembling, make a notch or pencil on the sides of both parts. Voila, you've created your own key with a little forethought.
