Set Back Double Posts At Outside Corner

How To Attach Double Railing Posts Set Back From Corner

Paired corner posts that are offset from an outside 90 degree corner are not a very common railing construction method and for a number of reasons. But if you have to set back a pair of railing posts at a corner, here is what it looks like.

Just imagine the challenge that is created by this building style with the large gap between the posts. A railing section has to continue on from each post and meet at the corner where no post will be.

This means the two bottom rail members must join together and be attached by way of a 45 degree miter cut or an side over end butt joint and screws.

It's an odd railing post arrangement.

But this is how you would do the blocking of the framing and attaching everything correctly.
