Product Description

Superior Outdoor Products Plain Vinyl Post Trim – Choose Your Size & Color

• Clean, minimalist base detail — Plain vinyl post trim finishes the bottom of your vinyl posts with simple, straight lines, without the extra ornamental shaping of Classic, Federation, or Modular trims.
• Economical finishing option — A budget-friendly way to cover cut edges, shims, and small gaps where posts meet the deck, porch, or stair surface while still delivering a neat, professional look.
• Multiple sizes for common post sleeves — Available for 4", 5", and 6" vinyl posts in White, Almond, Clay, and Black, plus 8" vinyl posts in White, Almond, and Clay so you can trim both standard and larger structural posts consistently.
• Coordinates with Superior vinyl railing — Designed to pair with Superior Outdoor Products vinyl posts, caps, and railing systems for a cohesive color match at the base of every post.
• Durable, low-maintenance vinyl — Vinyl (PVC) construction resists rot, peeling, and moisture, and only needs occasional cleaning to keep the post bases looking sharp.
• Trim only for flexible planning — Sold individually as post trim pieces so you can order exactly what you need for line posts, corners, newels, and stair posts; posts, caps, and mounts are sold separately.

The Superior Outdoor Products Plain Vinyl Post Trim is a simple, cost-effective way to give your vinyl railing and porch posts a clean, finished base. Each trim piece slides down over the post sleeve to cover cut edges and minor gaps where posts meet the deck, patio, or stair surface, helping your project look neat and professional without adding ornate detailing. Offered for 4", 5", 6", and 8" vinyl posts in multiple colors, this plain trim is a go-to choice when you want a streamlined base profile that complements any Superior vinyl railing style.

Why Choose This Plain Post Trim

• Simple, versatile profile — Straight, unornamented lines work with traditional, modern, or transitional railing designs.
• Budget-conscious upgrade — Provides the essential “finished” look at the post base while keeping accessory costs down.
• Helps hide installation tolerances — Conceals small gaps, shims, and fasteners at the base of structural or sleeve-over posts.
• One trim family for many posts — Use the same trim style across 4", 5", 6", and 8" posts to keep the base detail consistent throughout the project.

Specifications

Installation

Measure your vinyl post sleeves to confirm whether you need 4", 5", 6", or 8" Plain post trim before ordering. During installation, slide the trim piece over the top of the post sleeve (or follow Superior’s recommended sequence for your railing system) and lower it to the finished surface once the post is set plumb and secured. Seat the trim snugly against the deck, porch, or stair surface to conceal small gaps and fasteners and to create a consistent base detail across the entire run.

Buying Guide

• Start with post size — Choose 4", 5", 6", or 8" Plain trim to match your vinyl post sleeve dimensions.
• Pick a color to match or contrast — Use White, Almond, Clay, or Black (for 4", 5", 6") and White/Almond/Clay (for 8") to coordinate with your posts and rails.
• Plan one trim per post — Count line posts, corners, end posts, stair newels, and any newel posts on landings or transitions.
• Use Plain trim where you want a minimalist look — Choose Plain trim for projects that favor clean lines, and reserve Classic, Federation, or Modular trims if you want more ornament at the base.
