That's what it is, it's basically two boards with angled cuts to match. One mounted to the wall, the other to the thing you want to hang from the wall. No fasteners needed other than for those two attachments (or more if you use more boards). Gives you some flexibility in arranging things in a shop (or, that's my reason for using it with our 2-car garage).

I misunderstood the original message, seem's like my English isn't that good. Thanks for taking the time to explain!
