I installed two of these handrails on stone and masonry steps. Pro: Sturdy welded steel construction. Classic wrought iron looks. Good finish. Adjustable angle to fit stair rise. Includes lag screws for wood and masonry anchors. Con: Two of the four base plate covers were dented in shipping. Distance between posts is NOT adjustable, the pivot points are welded to the handrail. Masonry drill bit shown in the photo is NOT included. A 3/8" masonry bit and hammer drill are needed. The wrenches included in the kit will not apply enough torque to safely mount the posts. You need a 14mm socket wrench and a 4mm Allen hex key to install.
