Step 8 · Install Railings (Optional)
If your design includes railings, mark the locations for the railing posts on the stringers or treads. Typically, posts are attached to the outside of the stringers using lag bolts. Once the posts are securely in place, measure and cut the handrail material to span between posts or from a post to the end of the steps. Attach the handrail to the posts using appropriate fasteners, ensuring it is at a comfortable height (usually 34-38 inches above the tread surface).
