I was quoted at a door shop over $100 for a set of hinges similar to this. Thought that was insane and ordered these and couldn't be happier. The instructions are on the bag the hardware comes with and tells you the dimensions of where to mount the the brackets for the respective angles of opening. Yeah they're not great and you'll have to build the assembly yourself, but it's pretty self explanatory of where the parts go to build it.
