Superior Outdoors 400 Series 36" Whitmer Deckboard Vinyl Railing Gates – Choose Your Width & Color

• Deckboard-ready top rail — Features the same 400 Series top rail with a pre-attached aluminum deckboard receiver, so you can fasten a matching deck board on top for a clean, continuous drink-rail look (deckboard not included).
• 36" high gate for code-oriented rail lines — 36" tall gate is designed to integrate with 36" 400 Series Whitmer level and stair railing sections for a consistent, guardrail-ready perimeter when installed to code.
• Two useful widths — Available in 36" and 48" widths to cover common deck and porch openings, from standard walk-through gates to wider access points for furniture and equipment.
• Whitmer square aluminum baluster style — Uses 3/4" square aluminum balusters in the Whitmer pattern, giving the gate a sturdy, upscale look that matches adjacent Whitmer railing runs.
• 4" vinyl uprights — Gate leaf is framed with 4" vinyl uprights on each side for a solid, substantial feel; choose compatible 4" post caps separately to complete the look.
• Four popular railing colors — Offered in White, Almond, Clay, and Black to coordinate with 400 Series Whitmer rails and your deck color scheme.
• Boxed gate kit — Each kit includes the top rail with deckboard receiver, bottom rail, uprights, Whitmer balusters, and fasteners for assembling the gate panel; hinges, latch, caps, and cross brace (if needed) are sold separately.
• Made in the USA, engineered to perform — Manufactured in the USA from high-quality virgin vinyl with aluminum reinforcement as part of the 400 Series system, engineered to work in IBC/IRC-compliant railing layouts when installed per code and manufacturer instructions.

The Superior Outdoors 400 Series 36" Whitmer Deckboard Vinyl Railing Gate is the finishing touch for a deck or porch that uses the Whitmer square-aluminum-baluster infill and a deckboard-style drink rail. Built around the 400 Series top rail with a pre-installed aluminum deckboard receiver, this gate lets you run the same deck board across the top as the rest of your drink-rail system for a seamless, high-end look. With 36" height, 36" and 48" width options, and color-matched rails in White, Almond, Clay, or Black, it integrates cleanly into 400 Series Whitmer level and stair runs while providing a sturdy, low-maintenance access point.

Why Choose This Gate

• Perfect match to 400 Series Whitmer rails — Uses the same deckboard-ready top rail and Whitmer square aluminum balusters as your 400 Series Whitmer sections, so the gate blends into the railing line instead of looking like an afterthought.
• Ideal for drink-rail decks — The aluminum receiver plate on the top rail is pre-drilled for attaching a deckboard at regular intervals, helping keep the board snug to the rail and minimizing visible gaps along the gate.
• Flexible sizing — Choose a 36" gate for standard walk-through openings or a 48" gate where you need larger equipment, furniture, or grill access without compromising your railing style.
• Durable, low-maintenance construction — Vinyl rails and uprights with aluminum reinforcement provide long-term performance without the sanding, staining, or repainting associated with wood gates.
• Part of a code-minded system — When installed with compatible 400 Series posts, mounts, and hardware, Whitmer gates help maintain a consistent 36" guardrail height and infill pattern for code-oriented deck designs (always confirm gate and latch details with your local building official).
• Customizable top surface — Because deckboards are supplied separately, you can match your existing deck boards or introduce a contrasting top board to create a unique visual accent across the gate and rail.

Specifications

Installation

Lay out the location of your 400 Series Whitmer gate within the deck or porch railing line and verify required clear opening and swing direction before setting posts. Use properly anchored structural posts or post mounts sized for 4" vinyl sleeves at each side of the opening, following Superior's 400 Series installation instructions and local building codes. After posts are set, assemble the Whitmer gate by installing the aluminum balusters between the reinforced top and bottom rails and attaching the rails to the 4" uprights according to the gate kit directions. Mount hinges and the gate latch (sold separately) at the recommended heights and hardware spacing, then adjust the gate for smooth swing and proper latching. Once the gate is operating correctly, fasten a compatible deckboard to the pre-attached aluminum receiver plate on the top rail with the supplied fasteners, keeping the board centered and flush with adjacent drink-rail sections.

Buying Guide

• Choose your gate width — Select a 36" Whitmer gate for typical pedestrian openings, or step up to 48" where you need extra clearance for grills, furniture, or equipment.
• Match your railing system — Pair this gate with 400 Series Whitmer deckboard level and stair sections in the same height and color for a cohesive, continuous look across the entire deck perimeter.
• Plan posts and hardware — Make sure your opening has structural posts or post mounts capable of supporting the gate and hardware. Order compatible hinges, latch, post caps, and an optional cross brace (for wider gates or high-traffic conditions).
• Select your deckboard — Use a deckboard that matches or complements your deck surface. The 400 Series aluminum receiver plate is pre-drilled to simplify fastening and help keep the board tight to the rail.
• Consider code and safety — Confirm local guardrail, gate, and latch requirements (height, spacing, latch type, and child-safety rules) with your building inspector, and install the gate and hardware accordingly.
