Holds a post in place above a slab and looks nice at the same time.That said, it is not a beginner's best friend. Understand how it works. Take careful measurements. Drill accurately. And: I won't recommend this... But I used a chainsaw for the slot in the post! I am very happy with the results. FYI: I did use a wood saw to put a narrow, well placed, slot in the post before widening it with the more aggressive saw. ### ⭐⭐⭐⭐⭐ Very pleased! *by on Reviewed in the United States January 9, 2024* These worked great. There's a little learning curve on drilling the holes, but once you get it........These allowed the 6"x6"x16' posts to stand up without any bracing while getting the balcony parts lined up. --- ## 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.jp/products/89479521-2-pack-simpson-strong-tie-cpt66z-6x6-concealed-post-base](https://www.desertcart.jp/products/89479521-2-pack-simpson-strong-tie-cpt66z-6x6-concealed-post-base) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-12*
