I purchased one of these
I purchased one of these rails for an elderly neighbor who had a handyman install a cheap metal kit from one of the big box stores. It had rusted out and I was afraid she would fall if she accidentally leaned against it. The rail was very easy to install. I followed the directions and took me less than an hour. Very strong and sturdy. I am ordering another one for her since she wants one on the other side of the step. Hint- If drilling into concrete, rent or borrow a hammer drill. Saves a lot of time and effort.
