Need to build a simple handrail for some stairs. It's only 3 concrete steps coming off a porch. There's nothing on either side of the steps. I'm going to use a 4X4 wood posts. My question is how to secure the posts. I initially thought about just burying them in the ground beside the steps in about 2 ft of concrete, but then thought maybe it'd be easier to just attach the posts directly on top of the concrete steps. I know Simpson makes a few different post bases for this, but my question is - Will these post bases provide a strong enough attachment for lateral weight - ie someone leaning against the rail? Thanks.
