Review on 📞 Leviton N751-W 1-Gang Box Mount Telephone/Cable Wallplate, Horizontal Split Plate, White, 0.625-Inch Hole Device by Junior Rojas

This is exactly the solution to the problem. The actual center hole is 3/8" not the 5/8" listed in the description. There is a large 5/8 inch recessed area surrounding the hole that could probably be shaved or filed to that size if needed. Alternatively you can use it to install an o-ring or something else if you want to make the hole smaller to fit something smaller. I'm only giving 4 stars because this wall plate is made out of very thin plastic despite the fact that it costs 9 times more than a standard blank wall plate. markings) on the front of the locking fingers that hold the two halves together. This may or may not be an issue for you depending on where it is installed.
