Exactly as described! Snaps perfectly into place, sealing the hole. Doesn't stretch. Suitable for (at least) 2 wires 14GA. Maybe 3 if you really try, but I would suggest going up a size. Used in aluminum siding in the 73-foot Nomad Skyline (dubbed Galavant) RV with 2"Γ2" walls. (Picture: Wires are not in the sleeve - this is temporary!)
