• 【Precision Fit for 3.5" Actual Wood Posts】Our 4x4 Post Caps’ true inner dimension is 3.65" x 3.65" (92.6mm x 92.6mm) – designed for wood posts measuring 3.5" x 3.5" (standard 4x4 nominal lumber). Please measure your fence post caps’ actual width before ordering. For slightly oversized posts (up to 3.65"), light sanding ensures a snug fit
• 【Heavy-Duty Iron – Not Flimsy Plastic or Soft Aluminum】Unlike plastic caps that crack under UV or aluminum that dents easily, APONUO post caps 4x4 are crafted from thickened solid iron. Withstands heavy impact, snow loads, and accidental stepping. Provides true long-term protection for your fence, deck, or mailbox posts
• 【Triple-Layer Rustproof Coating – Built for All Weather】Electro-zinc primer + epoxy powder + weather-resistant matte black topcoat. Passes 500+ hours salt spray test. No rust, no fading, no peeling – even in coastal or high-humidity environments. The matte black finish adds a modern, elegant look
• 【Flat Top Trapezoidal Design – Modern Look & Extra Function】Unlike pyramid deck post caps with sharp points, our flat top with sloped sides offers a clean, contemporary appearance. The flat surface can hold small decorations (like solar lights or planters) and still efficiently sheds rainwater thanks to the 4-sided bevel. No pooling – water slides right off
• 【Easy Installation & Complete Kit】Each decking cap includes 2 carbon steel screws. Pre-drill pilot holes, place cap, and screw through the pre-drilled side holes. Works with standard power drill. No special tools required
