Review on 📺 WALI CM2665 TV Ceiling Mount: Adjustable Bracket for 26-65 Inch Flat Screens, VESA 400x400mm, 110 Lbs Capacity - Black by Adam Bates

If your template is 200x200 or smaller and you don't need extensions, this mount is for you. If your template is 400x400 or 300x300, it will likely work fine. If your template is such that you need to place extensions horizontally, stability can be an issue. Pay attention to the first photo of the manufacturer, which I have added comments to. The orange circles are where the extensions attach to the plate. Most mounts have two brackets on these joints, making them immobile. This bracket has only one fastener. The red dots represent my 400 x 200 template. As you can imagine, my installation sags under some stress; I need a precise fit and can't afford to let my TV sag even 1/4 inch. I exaggerated the last photo so you can see the effect.
