How To Install Paired Posts At Inside Corner

What do you do when you have doubled or paired posts at an interior 90 degree corner location? This requires some unique framing and bracing techniques and connector hardware if you plan to secure the posts to the deck joist structure.

Because adding a second rail post at an inside corner means you are bolting on to an adjacent joist or rim joists you have to add some significant blocking into the deck frame.

Here is a typical framing scenario at an inside corner for two posts and the hardware you will need.

Required Hardware And Cost

Building your deck railing in this manner is less common but you do see it occasionally. The reason is because it makes for a more complicated corner for the adjacent railing to connect together.

In addition to some good carpentry skills and labor, you have to get a lot of hardware and install it all properly. The end result though is a very strong double corner post arrangement.


This way of installing double corner posts can be well beyond the ability or desire of most people to install all this hardware, or notch the decking boards around each post.
