Superior Outdoor Products 200 Series 36" Whitmer Vinyl Stair Railing Sections – Choose Your Length & Color
- Whitmer square aluminum baluster stair infill — 200 Series Whitmer stair sections pair a flat vinyl top rail and rectangular bottom rail with 3/4" square aluminum balusters for a clean, modern look that flows naturally down your stair run.
- 36" stair guard height — Each Whitmer stair section is designed as a 36" nominal guard, a common choice for residential stairways where local codes allow 36" handrail/guard height.
- 6' and 8' stair lengths — Choose 6' or 8' boxed stair sections to match your stair layout; both can be trimmed to fit exact post-to-post openings on straight runs.
- Standard 32°–36° stair brackets — Included stair brackets are designed for typical 32°–36° stair pitches, simplifying installation on most deck and porch stairways.
- Standard Black balusters with upgrade options — Whitmer stair kits ship with 3/4" square Black aluminum balusters as standard; alternate baluster colors such as White, Bronze, or Kona are often available by special request and may require an upcharge and additional lead time.
- Multiple vinyl rail colors — 200 Series rails are offered in popular colors like White, Almond, Clay, and Black, making it easy to coordinate your stairs with matching level sections and your home's trim.
- Aluminum-reinforced, low-maintenance construction — Internal aluminum inserts in the top and bottom rails add strength for stair loading, while the exterior vinyl resists peeling, rot, and repainting.
- Professional-grade system made in the USA — 200 Series Professional Rail is manufactured in the USA from high-quality virgin vinyl and aluminum and is evaluated under Intertek CCRR-0167 for IBC/IRC guard applications when installed per the report and manufacturer instructions.
The Superior Outdoor Products 200 Series Whitmer Vinyl Stair Railing Sections give you the same contemporary, square aluminum baluster look as Whitmer level runs, carried seamlessly down your stairs. Each 36" tall boxed stair section includes a flat, approximately 3 3/16"-wide 200 Series top rail, a simple rectangular bottom rail with aluminum reinforcement, and a full set of 3/4" square Black Whitmer aluminum balusters, plus stair brackets sized for standard 32°–36° stair pitches. Available in 6' and 8' lengths and in rail colors such as White, Almond, Clay, and Black, Whitmer stair sections help you complete a coordinated railing system from deck to landing with professional-grade performance and low maintenance.
Why Choose This Stair Section
- Consistent look from deck to steps — Use Whitmer stair sections with Whitmer level sections so your square aluminum balusters and flat 200 Series rails match on every run.
- Modern, square-metal aesthetic — The 3/4" square aluminum balusters give the stairs a crisp, current look that pairs well with composite decking and contemporary architecture.
- Open sightlines on stair runs — Slim metal balusters preserve visibility to the yard, driveway, or pool area compared with bulky wood pickets.
- Flexible length options — Choose 6' sections for shorter stair runs or tight spaces and 8' sections to reduce the number of posts and brackets on longer stairways.
- Color and contrast control — Standard Black balusters create a strong contrast against White, Almond, or Clay rails; where available, special-order baluster colors like White, Bronze, or Kona let you fine-tune the look.
- Engineered for code-conscious projects — As part of the 200 Series Professional Rail system evaluated under CCRR-0167, Whitmer stair sections support IBC/IRC guard applications when paired with the proper posts, mounts, and installation details.

Installation
Start by planning your stair run and marking post locations at the top and bottom of the stairs, and at any required intermediate landings, according to local building codes. Install structural post mounts and 4" vinyl post sleeves so that posts are plumb and aligned with the stair stringers. Measure the angle and post-to-post opening for each run, then cut the 6' or 8' Whitmer stair section to length, maintaining the required rail engagement for the brackets. Attach the 200 Series stair mounting brackets at the correct heights and angles for a 36" guard on your 32°–36° stair, then set the aluminum-reinforced top and bottom rails into the brackets and secure them with the supplied screws. Install the 3/4" square Black Whitmer aluminum balusters into the pre-routed or pre-punched rail openings as directed in the installation guide, keeping spacing consistent along the rake. Snap on any bracket covers provided, then finish the project with matching post caps and base trim for a clean, finished appearance. For stairs outside the 32°–36° range or for ramps, use compatible universal stair brackets that adjust from 0° to 45°.
Buying Guide
- Verify 36" stair height is acceptable — These Whitmer stair sections are 36" tall; confirm that 36" guards are allowed on your stairs under local codes before ordering.
- Choose between 6' and 8' sections — Shorter 6' sections are easier to handle and generate less waste on shorter stairs, while 8' sections help reduce post counts and can be cut into multiple shorter runs when needed.
- Coordinate rail and baluster colors — Standard Black balusters work especially well with White, Almond, and Clay rails; if you want a lighter or more custom look, ask about special-order White, Bronze, or Kona balusters and any associated upcharges or lead times.
- Match level and stair runs — For a unified design, pair Whitmer stair sections with Whitmer level sections and choose the same rail and baluster colors throughout your deck or porch.
- Plan for brackets and accessories — Standard 32°–36° stair brackets are included; add universal 0°–45° brackets separately if your project includes non-standard stair pitches or ramp runs.
- Don't forget posts, caps, and trim — Build a complete system by adding compatible 4" post sleeves, structural post mounts, decorative caps, and post trim from Superior Outdoor Products.
