The lock has a special key that I would say is hard to pic. It’s thick steel and is powder coated I guess so it does not rust. Very satisfied with the purchase even though it was pricey but worth it. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars I was skeptical *by J***M on Reviewed in the United States on October 10, 2024* The price made me concerned, but this is an excellent, well designed product and it even looks cool. Leaving my travel trailer with this in place makes me feel it is secure and that it would take more than an angle grinder to remove it. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Super Solid *by Y***I on Reviewed in the United States on August 7, 2024* Material is strong, fit my Ram hitch perfectly! No ones getting that thing off. ## Frequently Bought Together - Proven Industries Model 2516-B Trailer Lock, Fits 2 5/16-Inch Bulldog or Ram Trailer Couplers, Made in The USA, (Black) - MAXXHAUL 70472 Solid Rubber Heavy Duty Black Wheel Chock 2-Pack, 8" x 4" x 6" - Proven Industries Model 400XL Puck-Lock Set, Made in The USA, Pack of 3, (Black) --- ## 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.vn/products/93701862-proven-industries-model-2516-b-trailer-lock-fits-2-5](https://www.desertcart.vn/products/93701862-proven-industries-model-2516-b-trailer-lock-fits-2-5) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-26*
