When you begin walking up a staircase, the newel post is the first, larger post that begins the stair railing and gives it strength and stability. Newel posts are available in a wide range of styles, sizes and colours. If you're putting a newel post on concrete, you're probably working in an exterior setting. Install your newel post first when constructing a stair railing, so the post can help stabilise the rest of the structure as you work.

  1. 1

    Place the unattached post anchor that comes with the newel post against the surface of the concrete where you intend to install the post.

  2. 2

    Drill four to eight holes, depending on the anchor, using a standard drill and a concrete drill bit that matches the diameter of the concrete screws. Drill each hole approximately 1/2 inch deeper than the length of each screw, using the anchor as a guide.

  3. 3

    Attach the anchor to the post according to the manufacturer's instructions. Install the post on the concrete by driving the screws through the holes in the anchor into the drilled holes in the concrete. Check the post for stability.

Tips and warnings

  • In the case of hollow vinyl posts, you may have to install rebar in the interior of your newel post. Rebar in newel posts should almost reach the top of the post and should stick out the bottom. Once the rebar is installed, use the placement of the pieces of rebar sticking out of the bottom of the post to figure out the placement of holes you need to drill in the concrete.
  • If you drill too deeply into the concrete, stuff a plastic bag into the hole, then fill it with liquid hydraulic concrete. Leave enough room in the hole for the screw.
  • Wear protective gear, such as safety goggles, when working with power tools.
