Bought to hang overhead scoring monitors in a bowling center. Sharp PN-B401 displays (39" diagonal, 32 lbs.). Had to fabricate adapter plates (plywood) since the commercial displays had an unusual bolt pattern (400 mm x 200 mm with cooling vents in the center area). Worked well and pleased with the mounts overall.
I used this to mount a TV in my motor home. The old TV was basically in a box attached to the ceiling between driver and co-pilot seats. Attached mount to floor of this "box", and held TV outside of this box (as it was a larger TV). Works great, held TV firmly. Ordered a second one for my other RV today.
Previously, I purchased a MI-4200 (smaller) unit for mounting a 24" TV under a cabinet and it was great. So recently, I purchased the MI-4222 model for another purpose, however. I used it to mount a 32" LED TV on TOP of a cabinet in out boat. The little feet that are supplied with new TVs are not stable enough to mount on a boat that bounces and rocks when underway. I mounted the bracket upside-down, secured it to the cabinet, tightened the "fold" feature securely and mounted the TV with the 4 screws. Wonderfully stable and secure. I know that this is not the purpose of the bracket, but it is performing well. Mount-It should consider a "table top" version for boats and RVs. I purchased another MI-4200 to similarly mount a 22" TV in another room in the boat. Great products!
