This is a cap I made to lock onto a shelf bracket common to big box home improvement stores in the United States. The bracket I designed this for is a 16 inch long unit. It is printed in two pieces and locks together. I used this to hang large items. I am unsure of the durability long term. I plan to hang items that are about 12 lbs. in weight from this. Items hung are all metal and have unfinished edges i.e. abrasive.
