Deck Rail Post Installation
 
1 Attachment(s)
I want to get suggestions on the best installation method for ceder 4x4 posts on the outside of the deck. I have included a image of the joist configuration at the corner of the deck.

The challenges I have to deal with are as follows: double outer band/rim joist, blocking for picture frame.

My perference would be to have one notched post in the corner instead of two on either side of the corner.

What is the best method to attach the posts? Can I use a 1/2" lag bolt? How about a Ledgerlok screw?

All ideas would be appreciated. Thanks!

THIS (fig 24-26) is how you're suppose to do it.

Thanks. I have that document and it is a great guide, but I don't think it tells me how to deal with the double rim joist and a 4x4 post. There is no space for a through bolt.

Am I missing something.

Why do you need a double rim?

Pack the 1" space, mount the post inboard or outboard and use 10" carriage bolts.

Unless I'm missing something.

I can definitely do that for the posts in the middle, but any thoughts on how to do that for the post on the corner with the 3" of board to deal with? I guess one option is to have two posts in the corner that are offset.

Needed a double 2x10 beam on the outside due to the span from the house/ledger to the posts.

You’re stuck using lags on that corner the way you have it configured now.

Lags are no longer allowed in “most” places now, but that depends what code your area follows, if any.

Your best bet is to ask your local inspector.

If lags are allowed ” x 6-6 ” would work fine.
