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. Decorex Hardware Heavy Duty Pineapple Post Cap – Standard 4x4 Lumber (Actual 3.5"x3.5") The 4x4 post is the most common post in residential construction — fence lines, deck railings, gate frames, mailbox posts, garden borders. They go up by the dozen and they take a beating year-round. The top of every one of them is exposed end grain — the single most moisture-vulnerable surface on any wood post. Left uncapped, moisture penetrates the core and rot works its way down from the inside out. By the time damage is visible, replacement is the only option. Decorex Hardware caps seal that exposure completely — and the pineapple top turns every post into a decorative statement. The most common post size — done right: 3.5"x3.5" is the actual dimension of standard 4x4 dimensional lumber after milling — the most widely used post size across North American residential construction. Decorex Hardware's standard 4x4 pineapple cap is precision-engineered to fit this exact dimension flush, with no gap, no rocking, and no shimming required. Thick-walled cast aluminum — not a marketing claim: Some competitors describe their products as "marine grade" without disclosing what the cap is actually made of. Decorex Hardware is straightforward — thick-walled cast aluminum, heavy gauge walls, powder coat applied directly to bare metal. No plastic core. No thin stamped shell. The weight difference is immediately apparent when you pick one up — and it means the powder coat bonds to a real aluminum surface rather than flaking off a plastic base after the first winter freeze. The pineapple design: The pineapple has been a symbol of welcome and hospitality in architecture for centuries. The Decorex Hardware Pineapple Post Cap brings that tradition to modern residential fencing with intricate diamond-faceted detail cast directly into thick-walled aluminum at the point of manufacture. Not a surface impression. Not a stamped texture. Cast in. Sharp, deep, and consistent across every cap. Elevates the look of any fence line, garden border, deck railing, or entry gate. Finish built for real weather: Electrostatic powder coat applied directly to bare aluminum, then oven-cured at high temperature. Creates a molecular bond between coating and metal that resists rust, UV degradation, chipping, peeling, salt air corrosion, and freeze-thaw damage. Matte black finish. No maintenance required season after season. Installation: 2 stainless steel screws with black-coated heads included. Can also be secured with exterior-grade construction adhesive or silicone for a completely fastener-free finish. Installs in under two minutes per post with no special tools. Suitable for residential, commercial, and contractor applications. Compatible applications: fence posts, deck railing posts, gate columns, mailbox posts, lamp posts, garden post pillars, newel posts, pergola posts.
