The metal strip ensures a horizontal position and is more recommendable than microwave brackets without bar; the risk that the brackets are mounted by the odd individual holes, I was just too big. Therefore, I would from buying individual microwave brackets, without bar, advise.
The processing of the welds; particularly from the front, is not just a masterpiece and the paint in silver color does not look so high.
The plugs I did not use and prefer using stable anchors with the supplied screws. And I have each 2 screws on each side attached; Thus, the holder with the microwave is stable.
However, the internal thread for the expulsion of the length should not be too tight, there may bend the sheet.
All in all, recommend the holding of a problem with a microwave placement in the kitchen.
