All of the models I found for making a shelf bracket were ok but for the amount of weight I needed it to hold, creating my own was the only option. In order to use this you will need a screwdriver that is longer then most normal drivers. I was able to find more then I needed at harber freight tools https://www.harborfreight.com/2-piece-super-long-screwdriver-set-34253.html Only $8.99 This bracket is double sided.
