    Product Description

    Catalyst Madison 5" x 5" Standard Posts — Routed for Element Reserve Rails (Line, Corner, End/Gate)

    • System-matched posts — Purpose-built for Madison Standard Horizontal Privacy Panels in smooth solid colors.
    • Three configurations — Choose Line, Corner, or End/Gate to match your layout.
    • 5" x 5" vinyl construction — Durable, low-maintenance posts with UV-stabilized color-through material.
    • Solid color coordination — Matches Madison Standard panels in White, Sand, and Gray.

    Catalyst Madison 5" x 5" Standard Posts are the structural backbone of the Madison Standard horizontal fence system. Each post is factory-routed to accept Element Reserve rails, helping keep top lines straight and sightlines uniform across long runs. Select line, corner, or end/gate posts to suit your plan, then finish with color-matched caps like our Standard Pyramid Post Cap. For gate openings, add 5" x 5" Gate Post Inserts to increase stiffness and hardware bite.

    Why Choose This

    • Clean aesthetics — Routed rail pockets minimize visible brackets for a crisp, contemporary look.
    • Layout flexibility — Line, corner, and end/gate options handle straight runs, turns, and openings with the same profile.
    • Low maintenance — Vinyl posts won’t need paint or stain; occasional soap-and-water cleaning keeps them looking new.

    Installation (Quick Steps)

    • Lay out centers — Mark post locations for Madison Standard panels (6′ or 8′ widths).
    • Set posts — Excavate to code, set 5" x 5" posts in concrete, and plumb; align routing toward the run.
    • Allow cure — Let concrete set fully before loading rails and infill.
    • Assemble sections — Seat the Element Reserve bottom rail, stack horizontal T&G infill, and cap with the top rail.
    • Finish — Install matched 5" x 5" caps; reinforce end/gate posts with inserts where gates are planned.

    Buying Guide

    • Match post type to layout — Count line posts for straight runs, corner posts at turns, and end/gate posts for terminations and gate openings.
    • Plan openings early — Gate posts take more load; pair with 5" x 5" Gate Post Inserts and rated hinges/latches.
    • Coordinate components — Use caps in the same color family, e.g., the Standard Pyramid Cap, for a cohesive finish.

    Frequently Asked Questions

    Are these posts only for Madison Standard panels?
    Yes. They are routed to accept the Element Reserve rails used on Madison Standard horizontal panels in smooth solid colors.
    Do I need different posts for corners and gates?
    Yes. Order Corner posts for direction changes and End/Gate posts at terminations and gate openings to match your layout.
    Will these posts match my panel color?
    They are designed to coordinate with Madison Standard’s solid-color palette (White, Sand, Gray). Choose the same color for a consistent look.
    Do post caps come with the posts?
    No. Caps are sold separately so you can select the profile you prefer (pyramid or New England) in a matching color.
    How do I keep posts from shifting over time?
    Use properly sized concrete footings, set posts plumb, and allow full cure before loading rails and infill. Reinforce gate posts with inserts.
