Around the rim are holes for hold down screws. I used a few but I don't think they are necessary. My cover is 6" down and I have driven my tractor over the top soil many times,so it is durable. **Q: Will this fit a norwesco 24 in by 20 in manhole extension?** A: This cover is designed to fit corrugated pipe with an inside diameter of 18". I would recommend looking at the technical drawing for this product on the manufacturers website to determine if it would fit your application: https://www.polylok.com/mwdownloads/download/link/id/320/ Seeing that this covers OD is only 20.57" I would say no to your question. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fit Perfect *by M***B on January 16, 2026* Fit Perfect ### ⭐⭐⭐⭐⭐ good quality cover *by D***H on June 13, 2026* very nice cover ### ⭐⭐⭐⭐⭐ PLEASED *by M***N on April 16, 2024* VERY sturdy and far less expensive than it's cast iron counterpart. First one ordered was too large. Second is PERFECT. Time will tell how it holds up. Only drawback was missing screws. (First one came with them.) Fortunately, I keep many types on hand. ## Frequently Bought Together - Polylok 18" Heavy Duty Cover/Lid for Corrugated Pipe (PN: 3007-HDC) - Polylok 24" Heavy Duty Flat Cover/Lid for Corrugated Pipe (PN: 3008-WEST) - Polylok 12" Heavy Duty Cover/Lid for Corrugated Pipe (PN: 3004-C) --- ## 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.sk/products/93591982-polylok-18-heavy-duty-cover-lid-for-corrugated-pipe-pn](https://www.desertcart.sk/products/93591982-polylok-18-heavy-duty-cover-lid-for-corrugated-pipe-pn) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-09-05*
