The posts fit perfectly and they are made of a thick and durable metal. ### ⭐⭐⭐⭐⭐ Very pleased with the purchase. *by M***S on May 19, 2025* High quality materials. Fit 4x4 post well. Looks good and easy to install. ### ⭐⭐⭐⭐⭐ Excellent Quality *by H***Y on August 10, 2025* Very good quality brackets but would not fit onto a new treated 4"x4" treated lumber post. I had to trim the end of the 4x4 posts to make them fit. I am sure the brackets would fit non -treated lumber just fine. ## Frequently Bought Together - Grehitk 4×4 Post Base 4 Pcs,Deck Post Brackets,Inner Size 3.5"x3.5" Thick Steel Fence Post Anchor Base,Black Powder Coated Heavy Fence Post,for Supports Porch Railing Post Holders Pergola Brackets - Eapele 20pcs Deck Railing Brackets Connectors for 2x4 Railing Wood Post with 120pcs Wood Screws --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.uy/products/510787826-4-4-post-base-4-pcs-deck-post-brackets-inner](https://www.desertcart.uy/products/510787826-4-4-post-base-4-pcs-deck-post-brackets-inner) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-05-21*
