I needed this for a rental apartment where the insurance insisted on a handrail being added. I was a bit skeptical at first as the stairs are wood, and it seemed as most of the reviewers on here used theirs with masonry or concrete steps. It turned out fine though and also did include the screws needed to mount on wood steps. I made sure to get at least 2 -3 screws for each post into the risers/ stringers rather than just the step itself, and it turned out very sturdy. The instructions are pretty useless, it's hard to tell from the tiny pictures what is what, I had the top and bottom post inversed at first. Also, the included wrenches are a joke, why even bother? The end product nicely matches existing wrought iron railing at the property for a very decent price.
