I ordered these holders to get my surround speakers on the wall. The boxes are not large, but still have a very good weight. These brackets wall installation was very easy. Holes, drill, plug in, screw, finished! The screws to screw the speakers to the brackets had to be somewhat shortened, but I did not find too bad because it's done on the vice in a few seconds. Otherwise the brackets make me a strong impression, can be adjusted well and the look is also fine. So for me, a good buy for a very good price! From me, saying a strong buy recommendation!
