Mount and Secure Post with Through-Bolts

What happens in this clip

Align the pre-drilled post with the holes in the stair tread. Insert the four through-bolts through the post and the tread. From underneath the tread, mount the bottom plate to the through-bolts and then fasten the nuts securely. This compresses the post to the tread, providing the necessary rigidity. Ensure all bolts are tightened to prevent any wobbling or movement.

Goal: Attach the railing post securely to the stair tread.

About the full video

This project provides a detailed guide on installing an aluminum stair railing system, focusing on securing posts to stair treads, installing universal angle brackets, and then fitting both pickets and tempered glass panels into the rails. The process includes preparing the stair treads, precisely marking and drilling for secure mounting, and correctly assembling the railing components to create a safe and aesthetically pleasing stair handrail.

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.
