Attaching a metal post bracket to a concrete slab.

It’s not that difficult to attach a wood handrail post to a concrete walk, patio or porch slab. Here’s how.

To attach a wood handrail post to concrete:

  1. Mark the location of the holes in a metal post bracket on the concrete.
  2. Drill holes in the concrete of the right diameter for lead shields using a masonry bit in a hammer drill.
  3. Insert lead shields into the holes in the concrete.
  4. Use lag bolts or screws to attach the metal post bracket to the concrete.
  5. Insert the wood post in the post bracket, and screw or nail it in place.

Danny Lipford: Robert writes, “How can I attach a wood handrail post to concrete?”

If you’re not as lucky as these homeowners and could mount your handrail post right down into the ground, then it’s a lot easier than you think to mount it to concrete.

This is one of the things that makes it really easy. It’s just a post bracket that attaches right to the concrete. Then you can put your post in place, even trim it out to make it look great.

How do you attach that to the concrete? Well, that’s pretty easy as well. It’s a lead anchor, basically a threaded sleeve, that you use a hammer drill and a sharp masonry bit to drill down into the concrete, you tap this in place.

Then, when you attach the bracket with your screws or bolts, it expands that lead anchor just a little bit and that’s where all of the strength comes in. And it makes it really easy to have a very strong post and one that will last for a long, long time.

    Looked all over for parts on Home Depot and Lowe’s site and cannot find proper base, or lag bolts (they seem threaded almost to the top of the hex bolt). Any help finding these parts would be greatly appreciated. Thanks!

    What if you do not have brackets and just want to tight one of the wood columns a bit loose? Does concrete nails exist or something similar?

    Where can you buy the exact brackets as shown in the video?
    We can only find the Simpson Strong Tie G185 4x Post Cap Z-Max – 4″ X 4″ and they are not as sturdy as yours.
