This low voltage insert was commissioned by a customer to fit their very specific conference room table. Typically the holes are circle or rectangle, but this one is an oval. The top of their table is also glass so it could not easily be modified.
The customer worked with me to take measurements, and I made and sent them the part. It is a very specific size, but you are free to use if you like with attribution.
