Remove the closet rod holders and rod from the closet. You have to cut off about 1" of the brown vinyl coating off the rod so the new rod holders will slide onto the rod. Wrap tape around the ends and middle of the steel pipe so it fits snugly inside the closet rod. Put the new steel rod holders on the rod and reinstall it in the closet.
