When they say "universal" they really mean it. It comes with so many different parts that it fits almost any speaker. Others have posted photos of the packaging and all the details, so I won't repeat that in my review. However, I would like to add: * I bought them to install surround back sounds. As you can see in the picture I installed them from the ceiling. * At first I was a little concerned that the mount would hold up, especially given the speaker's weight. *I started looking for studs/joists, but then I noticed that this kit came with aggressive drywall anchors.* There were 4 on each mount, and given the aggressive "teeth" they had no problem pinning the speakers to the to attach the ceiling. As mentioned, there are so many different options/adapters included in this kit to suit any type of speaker. So I still have a lot of unused parts left, but I'm sure I'll use them on other projects later. In general I am very satisfied.
