Tueascallk 32' Length White PE Plastic Edge Protection Strip, Toothed Press-in Edge Protection Sleeve, Suitable for Edges of 0.07"-0.085"(KG 020)

I had always dreading running wires through holes in sheet metal because it meant looking for/going out to buy whatever grommet I needed to fit the hole.I finally decided it was better to get 32' and make my own versus looking or going to get what I needed.I promise I now have a lifetime supply but it has already saved me several hours at the hardware store.Thanks,
