Fence Armor PostGuard™ (Post Guards)
Protect Fence Posts From Weed Whacker & Lawn Equipment Damage
Fence posts take the most abuse in any fence system. Lawn trimmers, weed whackers, lawnmowers, and landscape equipment slowly grind away at the base of fence posts, damaging wood, exposing rot protection systems, and shortening the life of the entire fence.
Fence posts are one of the most expensive parts of a fence to replace. Protecting them from weed whacker and lawn equipment damage can dramatically extend the life of the entire fence.
Fence Armor® PostGuard™ fence post guards provide a durable steel barrier that protects fence posts from landscape damage while improving the appearance of your fence.
Made from 22-gauge American galvanized steel and finished with a premium American polyester powder coat, Fence Armor guards are designed to withstand years of abuse from trimmers and mowers while maintaining a clean, professional look.
Whether you are repairing damaged posts or protecting a brand-new fence, Fence Armor makes it easy to prevent costly fence repairs and extend the life of your posts.
Protect wood, vinyl, and metal fence posts from weed whacker and lawn trimmer damage.

Built for Real-World Landscape Abuse
Fence Armor Post Guards are engineered specifically for the kind of abuse fence posts experience around lawns and landscaping.
American Steel Construction
Manufactured from 22-gauge galvanized steel for superior strength and long-term durability.
Premium Powder Coating
Finished with American polyester powder coating designed to resist scratching, fading, and weed whacker damage.
Deflection Design
The rounded radius corners help deflect trimmer filament, allowing landscapers to work faster while reducing post damage.
Protects Rot Protection Systems
PostGuard™ also protects exposed ground-line membranes such as RotGuard™ from mechanical damage.
Designed for New Fences or Existing Fences
Fence Armor guards use a two-piece design, allowing them to be installed in multiple ways:
✔ Install on existing fences to cover damaged posts and restore appearance
✔ Protect new fence installations from day one
✔ Install one side only where the grass meets the fence
✔ Install both sides for full 360° protection
This flexibility makes Fence Armor a favorite among fence contractors, HOA maintenance teams, landscapers, and homeowners.
