Product Description
Catalyst Sierra 3-1/4" x 3-1/4" x 8' Diamond Rail – Smooth White Vinyl
- Engineered 8' diamond rail — Each Sierra rail measures 3-1/4" x 3-1/4" x 8' long and is designed to install on the diagonal, creating the distinctive diamond-profile look of the Sierra Diamond Ranch Rail fence.
- Build 2-rail or 3-rail Sierra fences — Use two rails for a lighter, open ranch-rail appearance or three rails for a bolder, more defined perimeter along driveways, property lines, and entryways.
- Smooth, non-yellowing white finish — Standard smooth white vinyl is formulated to resist yellowing and stay bright across a wide range of climates with virtually no upkeep.
- Durable vinyl with SolarGuard® and StayStraight® — Manufactured with SolarGuard® fade-resistance and StayStraight® rail technology to help protect color and keep rails straight and aligned over time.
- Minimal, scenic ranch-rail style — Slightly angled square rails deliver a clean, modern take on ranch rail fencing that sets boundaries while preserving open views across lawns, fields, and sloping landscapes.
- Part of the Sierra Diamond Ranch Rail system — Designed to work with Sierra posts so you can build a cohesive, professional-grade Diamond Ranch Rail fence.
The Catalyst Sierra 3-1/4" x 3-1/4" x 8' Diamond Rail is the core component of the Sierra Diamond Ranch Rail vinyl fence system. Installed through routed Sierra posts, these square rails present a diamond-shaped profile between posts, creating a minimalist, elevated version of classic ranch rail fencing. Use two rails per section with the 60" posts for a clean, open boundary or three rails with the 84" posts for a stronger visual statement around driveways, rural acreage, community entrances, and pool or patio areas. Made from smooth, non-yellowing white vinyl with SolarGuard® fade protection and StayStraight® structural reinforcement, Sierra rails give you the scenic, post-and-rail look you want with the low maintenance and long-term performance you expect from professional-grade vinyl.
Why Choose This Rail
- Distinctive diamond look — Slightly angled square rails create a diamond profile that stands out from traditional flat ranch-rail boards, adding subtle, modern geometry to your fence line.
- Designed for scenic boundaries — Ideal for properties where you want to frame views, guide traffic, and define space without blocking sightlines—such as long driveways, pasture perimeters, and sloping landscapes.
- Low-maintenance alternative to wood rail — Unlike painted or stained wood rails, Sierra vinyl rails won’t rot, splinter, or peel, and they don’t require ongoing repainting or resealing.
- Flexible configuration — The same rail works in 2-rail and 3-rail layouts, making it easy to mix configurations across the property while using one SKU.
- Built-in fade and structural protection — SolarGuard® helps protect against UV fading, while StayStraight® engineering supports rail alignment across long runs.
- Made in America with warranty support — Manufactured in the USA and covered by a Transferable Limited Lifetime Warranty through Catalyst, for long-term peace of mind.

Installation
Install Sierra Diamond Ranch Rail posts at the spacing and depth specified for your layout and local building codes, typically set in concrete for stability. Once posts are plumb and the concrete has cured, insert the 3-1/4" x 3-1/4" x 8' rails diagonally into the routed openings in the posts. For 2-rail configurations, use one top and one lower rail; for 3-rail fence lines, add a centered intermediate rail. Keep rails level and consistently spaced along the run to maintain a uniform diamond appearance. Finish with your preferred 5" x 5" post caps to complete the look.
Buying Guide
- Determine 2-rail vs. 3-rail layouts — Choose 2 rails per section for a lighter, more open boundary or 3 rails for a taller, more substantial ranch-rail presence along roads and entrances.
- Calculate rail quantities — Multiply the number of fence sections by 2 or 3 depending on your configuration, and add extra rails for cuts, slopes, and transitions.
- Pair with Sierra posts and gates — Use Sierra-routed posts for proper fit and alignment, and plan matching gates where you need walk-through or equipment access.
- Match your site conditions — Sierra Diamond Ranch Rail is especially effective on sloping landscapes and scenic properties where open views and clean lines are priorities.
- Consider long-term maintenance — If you want the look of ranch rail without the upkeep of wood, these vinyl rails dramatically reduce lifetime maintenance costs.
