Did the holder on my Philips LED TV with a Philips 52PFL8605K02 HTL 3120 Soundbar mounted (not as shown above but below the TV)! Holders fit perfectly for this combination and can be prepared by the thoughtful design also well aligned so that the Soundbar nicely centered under the TV hangs. On mounting hardware everything is incl. Screws in various diameters.
The holders themselves are a bit thin and thus a bit wobbly with a mounted Soundbar. But since no one is going to make on the Soundbar pullups or otherwise somehow misused is negligible for me.
All in all, a fair offer (looking something other holders cost the likely lt. Of product image not even fit)!
