Install Stair Posts

What happens in this clip

For posts located on stair runs, careful measurement is needed to ensure alignment with the railing's angle. Take a measurement at the very bottom of the stair run and correlate it to the very top. This guarantees that the center slot on both posts will line up perfectly. Mark fastening locations, pre-drill the holes, and secure the posts with structural wood screws. Level the post thoroughly, adding shims if necessary, and then install the cover plate. Be aware that the corner post where the stair run meets the main deck might require a larger post bracket and careful alignment with speed squares due to the transition to a 90-degree angle.

Goal: Securely install posts on stair sections, accommodating the necessary angle.

About the full video

This project provides a detailed, step-by-step guide on installing the RDI Elevation Rail cable railing system from Barrette Outdoor Living on a deck. The process covers installing various types of posts (mid, corner, end, and stair posts), preparing and installing the pre-assembled cable rail sections, cutting and fitting top handrails, tensioning the stainless steel cables, and adding all final caps and trim.

Step 3 of 11: Attach Railing Posts

Position the railing posts over the pre-drilled holes. Use strong, corrosion-resistant screws or anchor bolts to firmly attach each post to the surface. Ensure the posts are vertical and stable. For wooden stairs, lag screws are typically used. For concrete or masonry, anchor bolts are required. Tighten all fasteners securely, but avoid over-tightening, which could strip the threads or damage the mounting surface.
