Do it right, and the pins should hammer into place. **Q: The description says the base can be cast-in-place. Does it come with the items necessary cast-in-place part? If not, what do you recommend?** A: The concealed post tie is a dry set, meaning it goes on top of cured concrete. You can anchor it the concrete with a wedge anchor, concrete screw or threaded rod with adhesive. Depending on load values or engineer specs you can use any of these options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Clean look, decent installation. *by M***L on April 16, 2025* These look nice and serve as a good base connections Cutting the kerf at 3/16” is not easy considering most blades are much thinner than that. ### ⭐⭐⭐⭐⭐ worked as advertised. *by P***L on November 30, 2024* No issues. My customer was happy. I'd probably go another route for my own application but they are good. ### ⭐⭐⭐⭐⭐ This is the real deal *by L***K on May 13, 2022* I purchased these post bases for a horse barn I am building. The hay loft which is very heavy will be held up with posts resting on these bases. That's a lot of weight. I only bought a few at first to check them out. Turns out they are very heavy duty and I trust them completely for my barn. They are exactly as presented in the ad. The quality and sturdiness is true. Just so you know my opinion. ## Frequently Bought Together - Simpson Strong Tie CPT88Z ZMAX Galvanized 8x8 Concealed Post Base 6-per Box - Simpson Strong-Tie - 2 Pack Simpson Strong Tie CPT66Z 6x6 Concealed Post Base with Pins & Washers by Simpson - Simpson Strong-Tie CPT66Z CPTZ™ ZMAX® Galvanized Concealed Post Base for 6x6 --- ## 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/60188056-simpson-strong-tie-cpt88z-cptz-zmax-galvanized-concealed-post-base](https://www.desertcart.jp/products/60188056-simpson-strong-tie-cpt88z-cptz-zmax-galvanized-concealed-post-base) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-11*
