Product Description
OZ-Fence® 3′ Post Extender — Fits 2-3/8″ (2.375″ O.D.) Round Steel Fence Posts
- Add Up to 3′ of Height — Extend existing 2-3/8″ posts for privacy, containment, or security without tearing out footers
- No-Dig Upgrade — Expanding internal assembly locks inside the post; twist the extender on and tighten for a clean, rigid connection
- Seamless Look — Smooth outer surface lets chain link or wood bracket hardware slide over with no exposed splice hardware
- Hot-Dip Galvanized Steel — Corrosion-resistant sleeve and extension built for long outdoor service
- Cut-to-Length — Use the full 36″ rise or trim to the exact height your project requires
- Gate-Ready Strength — Robust connection that many installers use even at gate posts (verify structure/load for your opening)
The OZ-Fence 3′ Post Extender is the fast, clean way to raise fence height using the posts you already have. Insert the expanding assembly into your 2-3/8″ O.D. round steel post, tension it to lock in place, and thread on the 3′ extension. There’s no digging, no demo, and no visible sleeve seam, so you can add privacy height, security toppings, or taller gates in minutes while keeping the original fence line intact.
Why Choose This
- Save time & concrete — Reuse existing footers instead of replacing posts
- Cleaner finish — Extension presents as a continuous post for bracketed hardware
- Flexible — Trim the extender to match step-downs, property lines, or partial-height upgrades

Buying Guide
- How much height? Use the full 36″ rise for 6′→9′ upgrades, or cut shorter for partial privacy increases.
- Gate considerations: The connection is robust; for wide/heavy gates, confirm post/footer capacity and use proper hinges/latch hardware.
- Nice-to-haves: Finish with a matching galvanized dome post cap; for privacy boosts, consider 2″ mesh privacy slats; for security upgrades, add Class III 12.5-ga barbed wire as permitted.
Frequently Asked Questions
- What size posts will this fit?
- It’s designed for standard 2-3/8″ O.D. round steel fence posts.
- How much height can I add?
- Up to 3 feet of added height; the extension can be cut shorter to suit your layout.
- Will my chain link or wood brackets slide over the joint?
- Yes—the extender presents a smooth outer surface so typical bracket hardware can slide over cleanly.
- Can I hang a gate from an extended post?
- Many installers do. Always evaluate gate width/weight, wind exposure, and footer condition to ensure adequate support.
- Do I need to remove my existing posts?
- No—the extender is designed to reuse sound, plumb posts so you can raise height without digging or new concrete.
