I sent this back to Revain as a hole where the locking mechanism was supposed to sit was misaligned. It's an inch or so. Attached image visible. Sounds like a quality control issue. Otherwise, this is a very heavy TV mount. I choose it for use in our transporter with a fifth wheel. The mounting screws provided would be too long for a standard RV wall thickness, so plan on buying shorter ones. The model number is MI-431.
