While a 2x6 may be suitable for use as wall framing, it is not suitable for use as a handrail as it does not give a properly graspable profile/shape which one can grasp when using the stairs, which could lead to a person falling down the stairs, which could lead to their surviving spouse calling me to ask why I did not tell them what I just told you, which would then lead to that surviving spouse's attorney calling you, after I reminded the surviving spouse that, indeed, I had noted this handrail in my report.
And, by the way, the handrail does not fully extend to the top riser as is required for safety.
