Product Description
400 Series Level Rail Mounting Brackets from Superior Outdoor Products – 4 Pack
- Designed for 400 Series level rails — Purpose-built brackets for attaching Superior Outdoor Products 400 Series level railing sections to posts, matching the drink-rail deckboard system used on Model, Madison, York, and Whitmer infills.
- Ideal for cut-down and repair work — Each 400 Series boxed section already includes brackets; these 4-packs are perfect when you cut one long section into multiple shorter spans or need to replace damaged hardware without buying a full kit.
- Hidden-fastener look — Brackets are supplied with fasteners and snap-on covers that conceal screw heads, complementing the 400 Series clean, no-visible-screws aesthetic when installed per manufacturer instructions.
- Compatible with 36" and 42" rails — Works with standard 400 Series code-evaluated level rail heights (36" and 42") and common lengths (6', 8', and 10') when installed according to Superior’s specifications.
- Color-coordinated to the railing system — Offered in the same core 400 Series railing colors (typically White, Almond, Clay, and Black) so brackets blend into the posts and rails instead of drawing the eye.
- Part of a USA-made, code-focused system — These are the same bracket components supplied in 400 Series boxed sections, which combine vinyl and aluminum construction and are ICC/ESR code evaluated when installed correctly.
The 400 Series Level Rail Mounting Brackets from Superior Outdoor Products give you the extra hardware you need to finish out custom layouts, repairs, and multi-span runs in a professional way. Each 4-pack includes the level rail mounting brackets and screws used in 400 Series boxed kits, so you can confidently attach aluminum-reinforced deckboard top rails and matching bottom rails to posts while preserving the system’s clean, hidden-fastener appearance. Whether you’re shortening an 8' section into multiple smaller spans or replacing brackets that were damaged, these color-matched brackets let you maintain a consistent look and performance across your entire 400 Series drink-rail installation.
Why Choose These Brackets
- Matched to 400 Series engineering — Uses the same bracket geometry and fastening pattern specified in Superior’s 400 Series installation guides, helping you stay within the tested system details.
- Clean finished appearance — Snap-on covers hide bracket screws, supporting the “no visible hardware” look called out in 400 Series specs and helping rails blend seamlessly into posts.
- Supports code-compliant layouts — When used with 400 Series ICC/ESR-evaluated rail sections and installed per the manufacturer’s instructions, these brackets help maintain a code-focused guardrail assembly.
- Great for custom spans — Extra bracket kits make it easy to cut down long level sections into shorter runs around bays, bump-outs, and deck transitions without sacrificing strength or aesthetics.
- Contractor- and DIY-friendly — Pre-engineered hardware, included screws, and snap-on covers reduce jobsite fabrication, speeding up installs for both pros and advanced DIYers.

Installation
Follow the current Superior Outdoor Products 400 Series installation guide for bracket placement and fastener schedules. After setting and plumbing your 4" post sleeves and structural mounts, mark rail heights on the posts and position each level bracket according to the layout for 36" or 42" guardrail height. Secure brackets to the posts with the supplied screws, then seat the aluminum-reinforced top and bottom rails into the bracket pockets and fasten them in place. Finally, snap on the bracket covers to hide screw heads and confirm that rail sections are level and firmly anchored before installing the deckboard on the top rail and any infill balusters.
Buying Guide
- Determine if you need extras — Order additional 4-packs if you plan to cut long 400 Series sections into two or more shorter spans, or if you’re replacing brackets from an existing run.
- Match your 400 Series color — Choose bracket color to match your 400 Series rails and posts (White, Almond, Clay, or Black) so the hardware disappears visually into the system.
- Plan rail layout first — Sketch your deck or porch and mark where posts and corners will land; count how many additional rail-to-post connections you need beyond what comes with your boxed sections.
- Confirm level vs. stair hardware — Use these brackets only on level sections. For stairs or ramps, use 400 Series stair or universal brackets designed for angled runs.
- Stay within tested details — Always follow Superior’s current installation instructions and any applicable code report details, especially for guardrails over elevated surfaces.
Frequently Asked Questions
What do 400 Series level rail mounting brackets do?
These brackets connect 400 Series level railing sections to the posts, securing the aluminum-reinforced top and bottom rails while maintaining the system’s clean, hidden-fastener appearance.
How many brackets are included in each pack?
Each kit includes four 400 Series level brackets with the necessary screws, which can support one or more short spans depending on your layout and how sections are cut.
Do these brackets include snap-on covers?
Yes. The brackets are designed to be used with snap-on covers that conceal screw heads, helping to achieve the “no visible hardware” look specified for 400 Series railing systems.
Can I use these brackets with both 36" and 42" 400 Series rails?
Yes. These level brackets are compatible with standard 400 Series level rail heights (36" and 42") when installed per Superior’s installation instructions.
When should I order extra level bracket kits?
Order extra 4-packs if you plan to cut full-length 400 Series sections into multiple shorter runs, or if you need to swap out damaged brackets during repair or remodel work.

Comparison
| Option | Key Strengths | Best Use |
| 400 Series Level Rail Brackets (this product) | Matched to Superior 400 Series rails with hidden-fastener covers and color-coordinated appearance. | Extra hardware for cut-down sections, repairs, and layout changes in 400 Series drink-rail installations. |
| 200 Series Level Rail Brackets | Sized for the 200 Series rail profile; ideal for standard vinyl rail applications without a deckboard top. | Projects using Superior 200 Series railing where extra level brackets are needed. |
| Generic off-brand brackets | May be inexpensive but typically lack system-specific engineering, matching colors, and snap-on covers. | Non-critical applications where appearance and code alignment with the 400 Series system are less important. |
| Field-fabricated blocking / fasteners | Customizable on site, but more labor-intensive and may not align with tested 400 Series details. | One-off repairs where factory brackets are unavailable, and a designer or engineer approves an alternate detail. |
To complete your 400 Series deckboard-style railing, pair these level rail mounting brackets with 400 Series boxed sections, matching posts, caps, trim, and any required stair or universal brackets.
