3.5" x 3.5" Heavy Duty Aluminum Pineapple Post Cap for True/Actual 3.5" x 3.5" Wood Posts - Black (Works ONLY with Actual 3.5" x 3.5" Posts. Will NOT Work with Actual 4" x 4" Posts)

• HEAVY-DUTY CAST ALUMINUM PINEAPPLE CAP – THICK WALLS, NO PLASTIC, NO THIN STEEL — Decorex Hardware post caps are cast from thick-walled aluminum — not injection-molded plastic, not thin stamped steel. Walls are substantially heavier gauge than competing caps at this price point. Intricate diamond-faceted pineapple detail cast sharp and deep directly into the metal — not stamped, not a surface texture that softens and wears away over time.
• FITS STANDARD 4x4 LUMBER ONLY – ACTUAL POST SIZE 3.5"x3.5" — Precision-engineered for dimensional 4x4 lumber posts that measure 3.5" on each side after milling — the most common post size in North American residential fencing, deck railings, and gate construction. Will NOT fit true full-dimension 4x4 posts measuring 4"x4". Always measure your actual post before ordering — do not rely on the lumber label.
• STOPS ROT & MOISTURE ON YOUR MOST COMMON FENCE & DECK POSTS — Standard 4x4 posts are used everywhere — fence lines, deck railings, gate frames, mailbox posts, garden borders. End grain absorbs rain, snow, and ice faster than any other wood surface causing rot from the top down. Decorex Hardware caps seat flush against the full post top creating a complete moisture barrier that stops damage before it starts and extends post life by years.
• POWDER COAT APPLIED DIRECTLY TO BARE ALUMINUM — NOT OVER PLASTIC — Competitors whose finish chips and peels are coating plastic or thin steel — not metal. Decorex Hardware powder coat is electrostatically applied directly to bare cast aluminum and oven-cured at high temperature creating a molecular bond that resists rust, UV fading, chipping, peeling, salt air, and freeze-thaw cycles. Zero maintenance. Zero touch-ups.
• INSTALLS IN MINUTES – WORKS ON FENCES, DECKS, GATES, MAILBOXES & MORE — Includes 2 stainless steel mounting screws with black-coated heads for a seamless finish. Also compatible with exterior-grade silicone or construction adhesive for a completely fastener-free look. No special tools needed. Perfect for standard 4x4 fence posts, deck railing posts, gate columns, mailbox posts, lamp posts, and garden posts.
