There is a design flaw in the railing. The installation instructions write that to screw the rails into the middle of the studs and that a wall with 16" stud spread must be used. I followed the instructions, lined up the first hole on the railing to the middle of the stud and found that the last hole on the railing is 31" from the first hole. This means that you can't screw the railing into 3 studs as instructed, there is not enough distance from first to last hole on the railing. The railing itself is 32", but that is little solace since the most important thing here is anchoring into the railing. I haven't yet searched for an alternative to this system, but I know this one is no good.
