Review on 🔌 10-Pack White Single Feed-Thru RG6 Bushings - Ideal for Coaxial Cable, Network Cable, CCTV - Indoor/Outdoor Rated - Replaces Wall Plates (Grommets) by Ryan Lawson

They are great for My goal is to install satellite speakers in the ceiling as part of a surround sound system. I routed the wires through the attic and routed them through the holes where each speaker was supposed to go. While connecting I slipped one of these over each speaker wire towards the ceiling and used a hole saw to slowly widen the rough hole in the ceiling until it was tight. I applied some caulk to the side facing the ceiling, pressed it into the wall, removed the excess caulk and used painters tape to hold it in place for a couple of hours until the caulk set. Now the speakers look great and the wire is coming out of that connection instead of the ugly black hole. Well worth the price - be patient, use a sealer and this is a great product for the purpose. Be aware of the size though - I embedded insulated 14g speaker wire in the wall and it's fine for this size. For bare/larger cable, you need the smaller size.
