• 36" or 42" stair heights — Choose 36" high sections for most residential stair applications or 42" high sections where a taller guard is preferred or required; always verify local code before ordering.
• 6' and 8' boxed stair sections — Available in 6' and 8' lengths that can be cut to fit your exact stair run while maintaining proper baluster spacing and rail geometry.
• York round aluminum balusters — Uses 3/4" round black York aluminum balusters for a clean, contemporary infill that pairs well with composite or wood decking.
• Aluminum-reinforced vinyl rails — Both top and bottom rails are vinyl with internal aluminum reinforcement for added strength and stiffness on sloped runs.
• Standard 32–36° stair brackets included — Kits include stair brackets sized for typical 32–36° stairs; for non-standard pitches, universal 0–45° stair mounts are available separately.
• Four rail colors — Offered in White, Almond, Clay, and Black to coordinate with common trim, siding, and decking palettes.
• USA-made, code-focused system — Manufactured in the USA from low-maintenance vinyl and aluminum and engineered as a guardrail system with third-party testing to IBC/IRC criteria when installed per current specifications.
• Complete boxed kits — Each stair section includes top rail with deckboard receiver, bottom rail, York round balusters, standard stair mounting brackets with screws, and an installation guide; posts, caps, trim, and deckboards are sold separately.

The Superior Outdoors 400 Series York Deckboard Vinyl Railing Stair Sections extend the 400 Series drink-rail concept seamlessly onto your stairs. Each boxed stair kit combines an aluminum-reinforced vinyl top rail with a pre-attached deckboard receiver, a reinforced bottom rail, and 3/4" round York aluminum balusters in black, creating a mixed-material look that feels at home on modern and traditional decks alike. Available in 36" and 42" heights, 6' and 8' lengths, and four rail colors (White, Almond, Clay, and Black), these stair sections let you carry a continuous deckboard-top railing from level runs onto your stairways for a cohesive, entertainment-ready design.

Why Choose This Stair Railing

• Continuous drink-rail look on stairs — The pre-attached deckboard receiver means your stair railing can match the deckboard-top look of your 400 Series level sections from landing to landing.
• York round baluster style — 3/4" round black aluminum balusters offer a slim, open feel and modern profile that frames views instead of blocking them.
• Flexible height and length options — 36" and 42" heights plus 6' and 8' section lengths give you the flexibility to meet common code requirements and lay out longer stair runs with fewer joints.
• Low-maintenance performance — Vinyl and aluminum construction won’t rot, splinter, or need repainting like wood; maintenance is usually limited to occasional cleaning.
• Code-conscious design — 400 Series rails are engineered and third-party tested as guard systems, helping installers and inspectors trust the system on stairways when installed per current specifications and code reports.
• Part of a coordinated family — Matches 400 Series York deckboard level sections, newel posts, gates, and mounting brackets for a consistent look across your entire project.

Specifications

Installation

Lay out your stair run and mark post locations based on 6' or 8' section lengths, accounting for landings and transitions. Install structural posts and 4" post sleeves according to Superior’s 400 Series guidelines and local codes, ensuring posts are plumb and properly anchored. Determine the stair pitch (typically 32–36° for standard stairs) and cut the 400 Series York stair section to length as needed, keeping the manufacturer’s minimum clearances at each end. Attach the included standard stair brackets to the posts and then secure the bottom and top rails to the brackets. Install the 3/4" round York balusters per the instructions, confirming spacing meets code, and fasten your selected deckboard to the aluminum receiver from below using the recommended fasteners. For non-standard stair or ramp pitches outside 32–36°, substitute 400 Series universal stair brackets (0–45°, sold separately) for proper alignment.

Buying Guide

• Select the correct height — Choose 36" stair sections for most residential applications or 42" sections where local code or project design calls for a taller guard height.
• Plan section lengths — Use 8' stair sections for long, uninterrupted runs and 6' sections where you anticipate landings, turns, or shorter spans; both can be cut to fit in the field.
• Match rail color to your design — White offers a clean, classic look; Almond and Clay complement warmer siding and stone; Black creates a bold, modern frame that pairs especially well with darker deck boards and balusters.
• Confirm bracket needs — For straight, standard-pitch stairs (32–36°), the included stair brackets are typically sufficient; for unusual pitches or ramps, add 400 Series universal stair mounts.
• Choose your deckboard — Decide whether the stair drink rail should match your main deck boards or intentionally contrast to highlight the rail feature.
• Don’t forget posts and accessories — Add compatible post sleeves, mounts, caps, post trim, and any ADA secondary handrail your code may require alongside the 400 Series system.
