what's up guys Mike from Rockville and today we are looking at the RHS b4 which is a pair of wall mount swivel brackets for satellite or bookshelf speakers each bracket can support a speaker up to 33 pounds similar brackets can only hold anywhere between 8 to 22 pounds in addition most similar style speaker brackets are made from plastic while our brackets are made from die cast aluminum making them truly commercial great the bracket swivel is 90 degrees left or right and can tilt 60 degrees up or down so you can point the speaker in virtually any direction needed so now with this flexibility it gives you a lot of different versatility with how you can use this mount you can use it in a home theater setup whether you have multiple speakers set up all across your room or any other bookshelf and satellite speakers you want to mount on the wall let's open this up and see what's inside and
