A:Answer Hi,
This stand is 52" wide. Although yours may be 51.2" wide, we base our recommendations on the standard TV measurement which is from corner to corner. It would still work, the biggest reason we recommend a max of 55" for the TV is to avoid any overhang which makes it easier to bump, and without knowing how wide the TV base is we can't confirm that it would fit. We hope that helps! Please let us know if you have any other questions!
