GRELWT Chain Link Fence Extenders 18-Pack — 25.2" Height, 1-3/8" U-Bracket Galvanized Steel, Adjustable Angle

GRELWT 18-pack fence extenders add 25.2" of height to 1-3/8" chain link top rails using a patented U-bracket for adjustable, secure extensions.

If you need a straightforward way to make an existing chain link fence taller—whether to keep pets safe, increase privacy, or deter wildlife—the GRELWT fence extenders provide a robust, tool-friendly solution. Each kit contains 18 galvanized-steel extenders with a U-joint bracket design that slides onto a standard 1-3/8" outer-diameter top rail and locks in place with included bolts and nuts.

How does the U-bracket design make installation easier?

The patented U-joint brackets are pre-shaped to fit over the top rail, so they push on and align without precise welding or custom bending. The third-generation updates increase side width and thickness to 1-3/8" and 3 mm respectively, giving a more rigid clamp when tightened.

• Push-on U-bracket fits around the top rail for quick placement
• Adjustable angle allows extension to tilt inward or outward as needed
• Includes bolts and nuts for secure fastening—tighten until stable
• Thicker 3 mm steel reduces bending when torque is applied

What dimensions and materials should I expect?

Each extender raises the fence by 25.2 inches from the top rail and is made from galvanized steel with a silver rust-resistant finish for outdoor longevity. The U-bracket is sized specifically for a 1-3/8" outer diameter top rail, matching common chain link standards.

• Extension height: 25.2" (from top rail)
• Bracket side width: 1-3/8" to match rail outer diameter
• Bracket thickness: 3 mm for improved stiffness
• Finish: galvanized steel with rust-resistant coating

Will these extenders keep pets and wildlife from getting in or out?

When installed correctly as a continuous barrier along the fence line, the extra height and inward/outward tilt options make it more difficult for dogs, coyotes, foxes, and other animals to clear the fence. They work best combined with proper spacing and secure attachment at each post junction.

• Added 25.2" height reduces jumping and climbing escape routes
• Inward tilt can discourage animals from scaling the fence top
• Galvanized coating resists weather to maintain deterrent function
• Use continuous installation for effective perimeter protection

What’s included and what tools or considerations are needed?

The package contains 18 extenders with U-brackets plus bolts and nuts. Installation requires basic hand tools (wrenches or sockets) and patience when tightening—third-generation brackets may need extra torque to hold vertical without loosening.

• 18 extenders per pack, bolts and nuts included
• Requires wrench or socket set for secure tightening
• Allow extra time to tighten brackets until they stay upright
• Check compatibility with top rail outer diameter before purchase

Who is this for: GRELWT’s 18-pack fence extenders suit homeowners, pet owners, and small-property managers who want a cost-effective way to increase fence height without replacing posts or chain link. They’re ideal when you need scalable, adjustable extensions that resist weather and hold firm under tension; choose this kit if your fence has a 1-3/8" top rail and you want a durable, installable solution delivered with hardware and support.
