This plan detail shows a stair landing guardrail and handrail assembly aligning with the stair stringers and tread nosing below. Vertical guardrail posts are spaced with a minimum six-inch dimension between them, and a bent closure plate is positioned below. The handrail loops around the outside of the vertical posts, maintaining compliance with a maximum four-inch spacing between balusters, guardrails, and balusters. Dimensions indicate a one-and-a-half-inch offset from the post centerlines to the outer handrail edge.
