The 10mm cedral plank is quite a snug fit. I don’t think you’d get anything bigger in it **Q: Will these work on 8” cedar clad 18mm thick at bottom edge.** A: Yes and no. It’s been made for cement board but you can unscrew 4 bolts and but another packers for thickness what you require ## Frequently Bought Together - PacTool Gecko Gauge, The Original Home Siding Installation Kit - For Use with 5/16 Inch Fiber Cement Siding and James Hardie Siding, Includes 2 Gecko Gauge Clamps - Diablo HardieBlade Saw Blade for Fiber Cement - 7-1/4" x 4-Teeth, PCD Tipped - D0704DH - PacTool SS724 Snapper Shear Pro - Cutting Tool for Fiber Cement Board - Power Shears Professional Power Tools --- ## 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.pt/products/59668063-pactool-sa903-gecko-gauge-mounting-kit-for-use-with-5](https://www.desertcart.pt/products/59668063-pactool-sa903-gecko-gauge-mounting-kit-for-use-with-5) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-02*
