      Frequently Asked Questions

      What is a newel post and where is it installed?
      A newel post is the large structural post at the top, bottom, or landing of a staircase that anchors the handrail system. It provides structural support for the railing and balusters, and is a primary visual element of the staircase design. Newel posts come in box, turned, and craftsman styles.
      What sizes are newel posts available in?
      Newel posts typically range from 3.5 inches to 5 inches square for the post body, with heights from approximately 42 inches to 60 inches or more. The finished height depends on the handrail height requirement and the post cap style. Windsor Plywood carries posts in standard sizes and can advise on sizing for your specific stair configuration.
      What wood species are stair posts available in at Windsor Plywood?
      Oak is the most common species for stair posts due to its hardness, grain character, and widespread availability. Maple and pine are also available depending on stock. Metal newel posts in square and round profiles are an option for contemporary and mixed-material stair designs.
      How are newel posts secured to the floor or stringer?
      Bottom newel posts can be bolted through the subfloor using a threaded rod and large washer anchored beneath, or surface-mounted using heavy-duty post base hardware. The method depends on the floor construction. A securely anchored newel post is critical as it bears significant lateral force every time someone grabs the railing.
      Can I replace just the newel post without replacing the entire railing system?
      Yes, in most cases a newel post can be replaced independently. The handrail attaches to the post with a rail bolt, which can be disconnected. The challenge is matching the new post style to the existing railing and spindle design. Windsor Plywood can help select a replacement post that coordinates with your existing stair components.
