Hey all, looking for a little bit of advice. I'm looking at putting in a small handrailing for my grandmother to help her get up her front 2 steps of her house. These are the steps: http://imgur.com/a/R0p0c . She currently is grabbing onto the corner of the bricks, which is a bit of a reach as there is a tree in front of it. I'm looking to put in a simple railing/handle on the steps to make it a little easier for her. My current plan is to grab 2 pieces of 4x4 and anchor it to the existing porch with deck screws, then put a small 2x4 or something across them and screwed into the 4x4's. I was planning to attach the 4x4's with L brackets. Wondering if this is an OK plan, or an absolutely terrible plan? Hoping to get a second look at it from people who know this stuff better than I do.
Thanks
