The tension rods may continue falling down for a variety of reasons. For instance, it can be that the walls are too slick and smooth to support them, that your wall cannot take the required strain, or that your rod is collapsing inward. Fortunately, these problems are simple to resolve. To give your wall the texture the rod needs to hold up if it's too smooth, you may purchase adhesive and rubber shelf mats. To protect your wall, you may also purchase tension rod holders. This is helpful whether you have drywall and are worried that the wall will crack if you twist the rod too much.
