I do know that the treated, and cedar 4x4 commercial posts that I used to construct a solar panel rack, worked just fine in these anchors. A really solid connection too. **Q: will drill hole in concrete to set these. what type of glue do I need to secure them & will it be possible to remove them in future? in t** A: You will need a strong cement glue,Amazon sell glue for these. it you have to remove it you mite have to use sawsall or angle grinder. **Q: where can I find these in 4 x 6?** A: Simpson does make them **Q: Can I pound these into dirt? I want to use with 4x4 garden totems?** A: You can but if the totems are too top heavy the anchor will pull out. You may want use cement. I used them to build a fence but I alternated the smaller anchors with 2 foot ground spikes in cement. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good buy *by L***T on January 28, 2025* Great price and very solid ### ⭐⭐⭐⭐⭐ Very good *by G***N on August 29, 2024* These worked well, and were less expense to what I could find locally. ### ⭐⭐⭐⭐⭐ Perfect for our use. *by L***S on August 15, 2024* Seems like good quality ## Frequently Bought Together - BISupply Concrete Post Anchor 4x4 Post Base Spike 4 Pack - U Shape Fence Post Holder Pergola Brackets Deck Post Base Set - Irwin Tools 1794482 Magnetic Post Level - U Shape Fence Post Holder Ground Spike Post Anchor Metal Black Powder Coated 4 Inches x 3.5 Inches Concrete Post Anchor Deck Post Base,1 Pack --- ## 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.dk/products/223424013-bisupply-concrete-post-anchor-4x4-post-base-spike-4-pack](https://www.desertcart.dk/products/223424013-bisupply-concrete-post-anchor-4x4-post-base-spike-4-pack) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-05-16*
