3″ full-height protection against weed-trimmer damage and rot.
Protect your fence posts from day one, and skip costly repairs later. Every fence is only as strong as its posts. That’s why Fence Armor’s Full-Protection PostGuard™ is engineered to keep wood or vinyl posts safe from the everyday hazards that destroy fences: weed-trimmers, lawn mowers, moisture, pests, rot, and impact damage.

Why it matters:
-
360° total coverage — The two-piece design wraps fully around square, rectangular, or round posts, sealing out moisture, bugs, and trimmer-string blows before they can damage wood or vinyl.
-
Tough, long-lasting steel construction — Built from 22-gauge North American galvanized steel, this guard resists cracking, rust, splitting, and UV damage. It’s ready for snow, sun, even heavy yard work.
-
Weed-trimmer safe radius design — The rounded edges protect your post and gently deflect weed-trimmer lines, reducing kickbacks and preventing gouges or nicks.
-
DIY-friendly installation — Quick two-piece design with color-matched screws included. Fits standard square or rectangular posts, whether you’re building new or upgrading the old ones.
-
Stackable & flexible — Add height, pair with RotGuard™, or top it off with our CapClaw post caps. PostGuards stack clean and lock in for full top-to-bottom protection. Perfect for hiding damage and bringing busted vinyl posts back to life.
Who this is for:
Homeowners, landscapers, and property managers who value longevity and low maintenance. Especially relevant for wood fences, vinyl or vinyl-wrapped posts, chain-link supports, mailboxes, pergolas, or any outdoor post exposed to string trimmers, lawn mowers, weather, or ground moisture.
The payoff:
Install this once, save hundreds (or thousands) down the road by avoiding rotted posts, cracked fences, or costly replacement. With minimal effort and affordable cost, your fence becomes a “set it and forget it” asset rather than a recurring maintenance headache.
