My mother the law had trouble with climbing our wooden steps due to the fact that the right railing was weakened. I threw a few of them down to secure the railing and they are as hard as rock! The only problem is that it is more secure now as the left side and my wife want me to level the left side and have already found a few things around the house that she wants to use them for, putting up shelves and stuff. I will probably order more as she is constantly inspecting the house looking for new fixes for me.
