Does this rust?** A: mine has been up and in the elements for 2 years in Oregon. We get a lot of rain. I have seen no sign of rust. **Q: would these work to secure an 8 foot tall pergola to pavestone?** A: I think they would work great for that. They are pretty heavy duty, and they are powder coated paint so they should hold up well outdoors. **Q: It says this is a 6”x6” post base, within the q&a I see a lot about 4x4 and even where it says the base is 6x6. Is this for a 6x6 post or 4x4?** A: The thin plate that mounts the support to another surface is 6" x 6". The upper part holds a 4' by 4" post. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars 6x6 is for a 6x6 *by G***R on Reviewed in the United States on November 22, 2019* This review is to clear up the confusion on the size.... People have been asking what size post fits the 6x6, and people are saying that 6x6 is the measurement of the base.Well that is totally wrong. 6x6 is for the post size. Which a 6x6 measures 5-1/2” x 5-1/2”. I didn’t measure the base, but the 6x6 is for a 6x6 and the 4x4 is for a 4x4. Hope this helps.As far as the quality, they are pretty darn good. They are strong and the paint is a very good quality. Almost feels like powder coated.I purchased these to replace a rotting 6x6 in my shed. I bolted the 6x6 to the concrete next to the rotting one. It worked perfect. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Just installed 8ft 6x6 post into one *by A***R on Reviewed in the United States on August 3, 2020* Holes for anchors to concrete are a bit below 7/16. I drilled mine out so I could use 1/2" anchors in fresh footings. Going through metal was easy enough to do with the right bit but the plate was thick and decent quality. I had planned to put bolts through the sides and the 6x6 but without them a post stands upright no issues when tightened with the 2 bolts in images. 6x6 nominal wood (5.5"Γ—5.5" actual) fit in these but I had to round the corners for a bit of ease dropping this in. Only have just done installation but they seem decently build and will last. 4stars due to the bottom plate could be a little bigger to accommodate 1/2" clearance holes which appears to be concrete anchor standard sizes. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Just what I wanted *by C***R on Reviewed in the United States on October 3, 2022* Great value and very well made- just what I wanted for my self built/ designed patio cover --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/88715184-6x6-inches-wood-posts-base-cover-inner-size-5-5x5](https://www.desertcart.us/products/88715184-6x6-inches-wood-posts-base-cover-inner-size-5-5x5) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-16*
