Galvanized Black Metal Post Caps – Weatherproof Protection

Why Choose Galvanized Metal Post Caps

Shield your wood fence and deck posts from Canada's rain, snow, freeze-thaw and UV damage with BarrierBoss galvanized metal post caps. Midnight Black finish on corrosion-resistant steel prevents moisture infiltration, cracking and decay while adding a sleek, finished look that lasts.

Pro Tip: Apply a thin bead of exterior-grade silicone under each cap before sliding it on for an extra-tight seal against water — especially important in Canada's freeze-thaw cycles and heavy snow regions.

Built to Withstand Canada's Harshest Conditions

BarrierBoss galvanized metal post caps are designed specifically for wood fence and deck posts, stopping water from pooling at the top and causing splitting, rot or decay. Crafted from high-grade galvanized steel with a durable Midnight Black finish, these caps offer superior rust resistance and a clean, modern appearance that elevates your fence line.

Fits standard wood post sizes: nominal 3.5"x3.5" (commonly sold as 4x4) and true 6x6. Each cap slides on easily and can be secured with screws for maximum hold — even in high-wind or stormy regions. No special tools needed.

Perfect for residential fences, rural acreage, decks, pergolas or garden borders where wood posts need reliable, long-term protection without constant maintenance or staining in Canadian weather.

Did You Know? Every BarrierBoss post cap is precision-cut and galvanized for all-weather defense, making them ideal for humid, rainy or sun-exposed climates across Canada.
