Determine Post Positions

What happens in this clip

Begin by determining the precise placement of all posts for the stair balustrade. Use a measuring tape to ensure that the posts are equally spaced along the stair run. A critical requirement is that the space between any two posts must not exceed 1.8 meters (approximately 5 feet 11 inches). Additionally, ensure that the chosen post locations are perfectly aligned with where the stair balustrade will be installed. The measurement for spacing should be taken from the center of the first post to the center of the last post to ensure overall accuracy.

Goal: Accurately plan the layout and spacing of balustrade posts for the stair system.

About the full video

This project provides a detailed guide on how to install the Peak Aluminum Balustrade Stair System, covering everything from initial measurements and post positioning to attaching rails, inserting balusters and spacers, and securing all components while adhering to local building codes. The system is designed to be high-quality, durable, and virtually maintenance-free.

Step 1 of 11: Layout Post Locations

Measure and mark the exact positions where each railing post will be installed. For stair sections, these marks should be made at consistent intervals along the slope of the stairs, typically 6 to 8 feet apart. Ensure posts are positioned to provide adequate support and to maintain the desired railing line. For landings, mark post locations at corners and along straight runs to meet code requirements and ensure structural integrity. Use a level to verify that the marks are plumb.
