18 Pack 1-3/8ft Chain Link Fence Extension 20ft Height - Post

Our review finds the 18 Pack 1-3/8' Chain Link Fence Extension is a practical option for homeowners who need a quick, durable way to raise the top of a chain link fence. The single biggest reason to buy is its combination of rust-resistant galvanized steel and a flexible U-joint that lets the extender attach at almost any angle, making it useful for keeping dogs and other animals from jumping out or intruding. In this review the extenders proved lightweight to handle yet solid in finish, and they include the basic hardware needed for a straightforward installation.

Key Features

• Galvanized steel construction: Provides a rust-resistant finish that helps the extenders withstand outdoor weather and extend service life.
• 17 in extension height: Adds substantial vertical reach to a fence to deter dogs and other animals from jumping over the top.
• U-joint design: Allows the extender to be pushed into the top rail and adjusted from vertical to 90 degrees for angled mounting and flexibility.
• Compatibility: Fits a 1-3/8' outer diameter chain link top rail and works with most standard chain link fences for broad application.
• Included mounting hardware: Bolts and nuts are supplied so the extenders can be secured quickly with simple tools like a hammer and gloves.
• Lightweight and portable: The frame thickness and materials make each piece easy to carry and position during installation.

Who It's For

This kit is best for residential users with existing chain link fences who want a low-cost, do-it-yourself way to increase fence height for pet containment or privacy screen attachment. It suits gardeners and small-scale livestock owners who need to protect plants from animals that can jump or climb.

Those who should look elsewhere include people seeking permanent, decorative fence upgrades or those who require welded, custom-fitted extensions for nonstandard rail sizes; this product is meant as a practical, adjustable extender rather than a finished ornamental solution.
