How to Attach Railing Posts to Deck Framing

When homeowners and DIYers build a deck, they often fail to attach the railing posts to the deck framing securely. A secure method of attaching railing posts to a deck is to notch the post at the bottom so it fit snugly in the space between the two outer floor joists.

The posts are then held in place with screws. Watch this video to find out more.


  1. The proposed approach would not meet code in many localities (e.g. Georgia). Posts should not be notched. Even with unnotched posts, with sufficient pressure at the top, the band/rim will break loose from the rest of the framing unless it is held to the nearest joist or blocking with a steel connector such as a Simpson DTT2 or USP DTB-TB.

  2. Bob Pond is absolutely correct. Building code does NOT allow posts to be notched. The Simpson DTT2 kit works well for cases where the posts are to be installed outside the rim/band joists. Not cheap, but sturdy and code-compliant. For posts installed internal to the rim/band joists, a series of blocking and technical wood screws does the trick. Again, never notch posts!

    • We wouldn’t think so, Mills. The structure of your deck should support the glass panels unless they’re extraordinarily large.
      Good luck!

  3. Hi, Ron,
    Our website reaches worldwide, so it’s always important to check your local building code before attempting a project.
    This tip will come in handy for some folks, but you’re right: This will not be an option for others.
