Really impressed with these: 1. Solid metal with chromed finish. 2. Perfect size to fit a UK 13amp plug through. 3. Easy installation. I recommend using a 57 or 58mm hole cutter to ensure a tight fit for the ring. I used an Erbauer Multi-Material Bi-Metal Holesaw 57mm (available in Screwfix). You have to press the rings in with this size or tap them lightly with a nylon mallet. 4. The inner disc uses two ridges to "lock" intro place when turning. So the disc is lose and easy to remove when required but is easily locked in place once the cables are installed. 5. The brush entry points keep debris out of the holes when cables are installed. 6. Looks very swish on the desk. Much better than black plastic versions.
Overall I recommend these as excellent quality and value.
