Corner Caps for Edsal Shelves Model UR-185WGB

I bought some storage shelves that have sharp edges on the uprights that stick up above the shelf, this is just a protective cap to cover the sharp edges.

My shelves are Edsal model UR-185WGB, they make shelves 36" wide by 18" deep and either two 36" high or one 72" high storage shelves. Other models from Edsal might have the same size uprights.
