Question: Is it just one bracket or a pair?
Document: I used these to hang an old long board skate board and use it as a shelf. I'm 40 now, and the skate board is calling my name. What better way to prevent myself from using it again, than to make it into a shelf! I'll try to include a picture, but you can hardly see the bracket over the awesomeness of my shelf!
These were easy to put up and look great. I bought my glass shelves from a glass company (online) and they look beautiful! Substantial weight and beautiful design that fits any decor.
These brackets look great but also hold a ton of weight as long as you screw into a wall stud. The supplied screws are cheap metal and I torqued the heads right off. Not fun digging the threaded shaft out of your wall. I recommend replacing them with stainless steel screws.
The brackets are GREAT. They look good and are very strong. The only thing that was wrong were the screws. They stripped out even after drilling holes. So be sure to have backup ones so you can complete the job.
Stylish, unique, classy. Makes for a great entry piece by my front door. Easy install. I'm very pleased and satisfied.
Reluctant at first to use the spacers they provided because I thought it would make it difficult to remove and re-install should I need to do so for cleaning. Turns out that's not an issue. Very happy with the results once installed.
Just the thing needed for a classy shelving display in my kitchen. Very easy to install, and holds the shelves in place securely. I used glass shelving between two cabinets for extra storage of some attractive glasses and dishes. Looks great!
I needed something strong to hold up three shelves I wanted installed in my kitchen. These fit the bill perfectly!
Answer: It is a pair.  PLEASE make sure the glass you are using is thick enough...3/8-1/2 glass is about 3-4 times the thickness of window glass.
