This is a replacement bracket for a white nylon one that broke on my cupboard wire shelf. The shelf was bought maybe 10-15 years ago and I'm not sure if they're even made anymore. The original bracket wasn't even designed properly to begin with and failed over time.
This one holds both vertical and horizontal wire points which prevents the rack from moving in any direction when screwed onto the inside of the pantry door. I used 6 of them which is plenty strong enough to hold 20 pounds of miscellaneous containers and spices.
You may need to drill out the hole depending on the size screw you use.
This was designed using TinkerCad.
