Product Description

Aluminum Acorn Chain Link Post Caps — Decorative Caps for Terminals, Corners, Gates & Line Posts (No Top Rail)

• Clean, Finished Look — Classic acorn profile dresses terminal, corner, gate and line posts where no top rail is used
• Rust-Proof Aluminum — Won’t rust like steel; great for residential and coastal installs
• Press-Fit Design — Slips over the post and seats securely; no extra hardware required
• Protects the Post — Helps keep water and debris out to reduce internal corrosion
• Full Size Range — Options for common chain link post O.D.s from 1-3/8″ up to 6-5/8″

Finish the tops of your chain link posts with rust-proof aluminum acorn caps. The decorative shape provides a clean, professional appearance while helping to keep moisture and debris out of the post. Installation is simple—press the cap onto the post and tap with a rubber mallet to seat. For line posts with top rail, use loop caps (eye-tops) instead.

Why Choose This

• Corrosion resistant — Solid aluminum for long outdoor service life
• Fast install — No bands or screws; press-fit saves time on every post
• Lightweight — Easier handling than pressed-steel caps
• Flexible usage — Use on terminals, corners, gates, and line posts where no top rail is used

Specifications

Installation

Confirm post O.D. and select the matching cap. Ensure the post top is round and free of burrs. Place the cap over the post and press down; tap with a rubber mallet until fully seated. If the fit is loose due to post wear or slight ovaling, lightly crimp the post top or use a thin bead of exterior-grade sealant to improve grip.

Buying Guide

• Select by post O.D.: Choose the cap size that matches the actual outside diameter of your post.
• Line-post usage: Fine for line posts when you’re not running top rail (e.g., tension-wire-only fences). If you’ll run top rail, use loop caps.
• Aluminum vs. pressed steel: Aluminum won’t rust and is lightweight; pressed steel is heavier and common on high-traffic sites.
• Barbed wire sections: Replace acorn caps with barb arms where barbed wire is required.

Frequently Asked Questions

Can I use these on line posts?

Yes—use acorn caps on line posts when you are not running top rail. For top rail, choose loop caps (eye-tops).

Do I need hardware to install them?

No. They are press-fit. A rubber mallet helps seat the cap securely.

Will these rust?

No. They’re aluminum, which is naturally corrosion resistant.

Do they work with barbed wire?

Use barb arms instead of acorn caps anywhere barbed wire is installed.

Will the color match my fence?

The cap is aluminum/silver. It coordinates with galvanized systems and can be painted to blend with color systems if desired.
