6x6 Aluminum Deck Post Base Cover (Actual 5.5x5.5) - Split Post Skirt

Our review of the 6x6 Aluminum Deck Post Base Cover finds it best suited for homeowners and contractors who need a quick, durable way to hide exposed post anchors and tidy up railings without rebuilds. The single biggest reason to buy is the split, snap-on design paired with one-piece cast aluminum construction and powder baked paint, which together deliver a rust-resistant, weatherproof cover that installs fast and looks clean. For anyone who wants a low-effort cosmetic fix for deck or porch posts, this set of two post skirts offers a practical, long-lasting solution.

Key Features

• High-quality aluminum: One-piece casting molding provides a sturdy, corrosion-resistant shell that stands up to outdoor exposure.
• Powder baked finish: The 50% matte surface resists moisture and fading for a consistent appearance over time.
• Split design: Two-piece skirts snap around existing posts so you do not need to remove railings or disassemble the structure to install them.
• Secure installation: Screw locking and a fixing adhesive on the bottom reduce shifting and keep the cover aligned on the base.
• Accurate sizing: Designed for nominal 6x6 posts (actual 5.5in x 5.5in) with a 9in x 9in base and 2in height to conceal anchors and defects.
• Two-piece pack: Includes two post base covers so you can finish a small section or pair of posts without buying extra parts.

Who It's For

These post base covers are ideal for homeowners doing cosmetic updates on decks, porches, stairs, or patios who want a fast, noninvasive fix. Contractors and handypersons will appreciate the split skirt and snap-on installation for retrofit jobs where posts stay in place. The covers work well where moisture resistance and a clean matte black look are desired.

Those who need exact tolerance fits should measure carefully before buying: some customers reported a quarter inch variance in fit on certain posts. If you require decorative trim beyond a simple base cover or a different color/finish, a custom or painted solution may be a better option.
