So I have to say that these owners are really great here. had only ordered the other really endured nothing. the adjustment of these holders is really top notch. they are made entirely of metall.aleine are panels made of plastic. screw through a long M8 they are 120 degree swivel and 20 degree neigbar.obwohl I must be more than 20 degrees inclined habe.man only Unscrew the large circular adjustment nut, then they loose 30 degrees or more verstellbar.nachdem you set everything you draw simple the M8 screw fest.dann pretending nothing pure more.The are then bombenfest.nicht like cheap plastic models of other manufacturers. holding my opinion out after more than 10 kg. are really good and thick sheet they gebaut.habe for my Souround boxes (CAT) in the middle of the room on the walls next Window and door aufgehangen.und these are not small satelitten.das are bookshelf speakers. 8kg per box. The trick: each holder a single sheet has thereby that one Moors on the box. a quasi adapter.hat the advantage that you only the fastener to the wall firmly screwed and then the box with adapter ind the bracket to the wall einsteckt.die box one can have so unscrew without something can abnehmen.so from the wall bracket to very easy the cable screw to the box and then just hang on the wall. a bag of 20schrauben and anchors is also dabei.schrauben in various lengths and durchmessern.ich have only used 4 :-) 1A massive wall bracket Price for top. Strong buy recommendation
