These end caps are needed for Shelf & Rod shelving only.
These end caps will fit onto the front lip of Shelf & Rod shelving and hide those cut ends that will snag clothes etc.
Unless you have an 'open end' or floating end, you will need 4 of these large end caps per shelf that you end up with, in addition to 203 - small plastic end caps.
If you are creating an open end shelf, please go to 168 - open end caps
