The wall mount system is very weak and poorly designed. The ad description says the shelf will hold 25 lbs.. I will not put 25 lbs. of valuable items on this shelf. these 3/16" dia. rods are far to small to hold up these shelves. The lead anchors are not meant to be reversed and reinstalled. I had to use different anchors to hold the rod brackets to the wall. Not impressed with these hidden bracket shelves. Would not recommend them.
