Laid out the chrome trim for the carpet to vinyl separation. I did not just blindly use the prepunched template holes on the cardboard backer and punch through the vinyl. I marked my spots with a marker on the front and used a drill with an 1/8” bit to drill a hole for each clip from the front right on the transition from carpet to vinyl. If you do this be sure to keep the drill bit from grabbing the carpet and pulling it. You will see in the next photo why I did it this way.
