Superior Outdoors 400 Series Whitmer Deckboard Vinyl Railing – 36" Level Sections, 6' & 8' Lengths, Multiple Colors

• 400 Series drink-rail ready top rail — Features the 400 Series vinyl top rail with a pre-attached aluminum deckboard receiver so you can add a matching (or contrasting) deck board for a wide, functional drink rail surface.
• Whitmer square aluminum balusters — Uses 3/4" square aluminum Whitmer balusters for a crisp, modern infill that offers stronger visual definition than vinyl spindles while keeping sightlines relatively open.
• 36" level height with 6' & 8' sections — Standard 36" guard height and 6' or 8' level spans fit most residential decks and patios; 10' lengths and 42" heights are available in the 400 Series system by special request for select layouts.
• Color options to match your project — Offered in White, Almond, Clay, and Black so you can coordinate railing with trim, windows, and decking for a cohesive outdoor design.
• Aluminum-reinforced rails — Both top and bottom rails are reinforced with internal aluminum channels to improve stiffness, reduce deflection, and support the added weight of a full-length deckboard drink rail.
• USA-made vinyl & aluminum construction — Manufactured in the USA by Superior Outdoor Products from low-maintenance vinyl and structural aluminum, designed for long-term outdoor performance.
• Code-oriented design — Part of a railing family engineered and third-party tested to meet IBC/IRC guardrail criteria when installed per manufacturer specifications and applicable code reports.
• Boxed level kits — Each level section kit includes the aluminum-reinforced top rail with deckboard receiver, bottom rail, Whitmer balusters, level brackets with screws, and installation guide; posts, caps, trim, mounts, and deckboard are sold separately.

The Superior Outdoors 400 Series Whitmer Deckboard Vinyl Railing brings together a robust drink-rail-ready top profile with clean 3/4" square aluminum Whitmer balusters for a premium, entertaining-focused deck railing. These 36" level sections in 6' and 8' lengths are ideal for decks, porches, and balconies where you want a flat, usable top surface that can support glasses, plates, and décor while still meeting typical residential guardrail requirements. With aluminum-reinforced rails, a pre-attached deckboard receiver, and a choice of White, Almond, Clay, or Black rails, the 400 Series Whitmer system lets you coordinate with your deck boards and trim while providing a strong, low-maintenance, USA-made railing solution.

Why Choose This Railing Section

• Purpose-built for drink rails — Unlike improvised drink-rail add-ons, the 400 Series is engineered from the start with an aluminum receiver plate that accepts a full-width deckboard along the top for a sturdy, gap-free drink rail.
• Modern square-baluster look — Whitmer’s 3/4" square aluminum balusters deliver a contemporary, linear aesthetic that pairs well with modern homes, composite decking, and mixed-material designs.
• Flexible design with your deck boards — Because the deckboard is supplied separately, you can match the exact decking product (and color) used on your project or create a contrasting drink-rail accent.
• Low-maintenance performance — Vinyl rails and powder-coated aluminum balusters resist rot, peeling, and most weathering; routine cleaning with mild soap and water is usually all that’s required.
• Professional grade construction — Aluminum reinforcement in both rails and a robust receiver plate make this a fence-contractor and deck-builder friendly system designed for real-world use.
• Part of a complete railing family — Pair Whitmer level sections with matching 400 Series Whitmer stair sections and gates (where offered), plus compatible posts, caps, and trim, for a fully coordinated deck perimeter.

Specifications

Installation

Lay out your 400 Series Whitmer railing runs and locate post positions based on 6' or 8' section lengths plus gate openings and corners. Install structural posts and 4" post sleeves according to Superior’s installation instructions and local building codes. Once posts are set, measure between posts, cut the Whitmer level section to length if needed, and attach the bottom and top rails using the provided 400 Series level brackets and screws. Install the 3/4" square aluminum balusters per the kit instructions, ensuring consistent spacing and plumb alignment. After the rails and balusters are secured, fasten your chosen deckboard to the pre-drilled aluminum receiver plate on the top rail to complete the drink rail, then finish with compatible post caps and post trim.

Buying Guide

• Choose 6' vs. 8' sections — Use 8' sections to minimize joints along long deck edges, and 6' sections where shorter spans or more frequent posts are desirable for layout or code reasons.
• Plan your deckboard drink rail — Decide whether you’ll match the existing deck boards or use a contrasting color/texture; confirm deckboard thickness and fastener type to ensure compatibility with the aluminum receiver plate.
• Coordinate color and metal finishes — Select White, Almond, Clay, or Black rails to coordinate with house trim and choose complementary baluster, post cap, and post trim styles to complete the look.
• Confirm height and code requirements — Verify whether your project calls for a 36" or 42" guardrail (where available) and ensure post layout, mounting hardware, and baluster spacing all meet local building codes.
• Pair with matching components — Combine these Whitmer level sections with compatible 400 Series stair sections, gates, posts, caps, post trim, and lighting to build a cohesive railing system across your deck.
• Review warranty and documentation — Consult Superior Outdoor Products’ installation guides, technical resources, and warranty information for full performance details and maintenance recommendations.
