Those jack holders are everywhere, but I did recently order one for home because I can’t find my other one. Had to order 6 inch shielded cables for a cable/network tester that I just bought and decided o go ahead and toss in another of those holders. Invaluable if you have more than a hand full of them to punch. They also keep the jacks from damaging sheet rock walls when you are punching short cables near a box. Found this out the hard way years ago and used to carry a metal box cover with me , until I bought one of the holder.
