This is another ingenious invention and product by Anel Standard. These plastic hive corner protectors are designed to protect the corners of your supers from the constant prying we apply to separate the supers. This repeated prying on the corners damages them to such an extent, that bees can eventually escape through the indentions left by our hive tools. With these corner protectors you will not have this problem as they will stay solid and show no wear. Make sure they are always where they need to by nailing or gluing in place.
