Review on 🔒 Expanding Round Locking Addlike Plugs by Hector Liamsi

I used these as jacks to neatly route the audio cables behind the truck bed. Being blank and 1″ in diameter makes it easy to drill holes in the platform as well as drill specific sized holes for different sized wires and also makes it easier to drill out unnecessary holes after changing amps/removing passives to stuff crossovers.
