4 Pcs Post Base Post Brackets 5.6x5.6 in - Heavy Duty Black Steel

Our review of the 4 Pcs Post Base post brackets finds them best suited to homeowners and tradespeople who need a robust, long-lasting anchor for 6x6 wood posts. The single biggest reason to buy is the solid steel construction and black powder coat that together protect the post from moisture and provide a neat, finished look; this review focuses on durability, fit, and the included fasteners so you know what to expect before installing them on a deck, fence, or mailbox post.

Key Features

• Solid steel construction: The heavy duty thick steel body gives the base structural strength for supporting porch railings, pergolas and other vertical loads.
• Black powder coat: A rustproof finish helps resist corrosion and keeps the brackets looking clean over time when exposed to the elements.
• Separated design: A partition at the bottom keeps the wood post isolated from ground contact to reduce the chance of rot from rain and splashed water.
• Stabilizing center box: A small square box in the middle of the base improves lateral stability for the 5.6 x 5.6 in post it is designed to fit.
• Complete fastener kit: The package includes a wrench, expansion anchors, socket head wood screws and self-tapping screws so the bracket can be mounted to concrete or wood without hunting for hardware.

Who It's For

This product is aimed at DIY homeowners, deck builders and contractors who need a sturdy post anchor for 5.6 x 5.6 in wood posts used on decks, fences, pergolas, gazebos and mailbox posts. The rustproof finish and isolated bottom design are useful for outdoor projects where moisture exposure is expected.

Those who need a bracket for nonstandard post sizes or who require a decorative ornamental base should look elsewhere, since these brackets prioritize strength and moisture separation over decorative detailing and are sized specifically for 5.6 x 5.6 in posts.
