The sides aren’t slotted there is four holes drilled into the sides. I’m using 4”x4” posts and I have had to pack out this extender as it’s maybe 5mm too big on two sides. As I’m putting a fair amount of weight onto it I don’t want it to shift and become loose. I hoped it had a plate inside to locate onto the post but it is a sleeve. ## Frequently Bought Together - 1 x 100mm x 100mm (4" x 4") Fence Post Extender - BPC Fixings Galvanised Panel Clip 16-Piece Set, 50 mm Size - TIMCO Timber Screw – Hex Head – Exterior Green – 6.7 x 100 - Box of 50 --- ## 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.com.ar/products/104204099-1-x-100mm-x-100mm-4-x-4-fence-post](https://www.desertcart.com.ar/products/104204099-1-x-100mm-x-100mm-4-x-4-fence-post) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-03*
