Insurance company approved which is the important thing to consider, cheap units generally are not approved by insurers as a legitimate tow hitch security device. Be mindful when buying a hitch lock that there is little point of skimping on a cheap hitch lock to secure a significantly priced asset! I do not see the point! Review: Simple to use. Hopefully it will deter a potential thief, but if they really want it.... There are other travel trailers in the storage unit without locks, so easy pickin's. ## Features - DUAL RATCHET SECURITY – Advanced dual ratchet locking system ensures a strong, tamper-resistant fit for maximum trailer protection - MULTI-USE DESIGN – Functions as both a coupler lock and a U-lock, providing versatility and convenience for securing your trailer or other equipment - 360Β° PROTECTION – Designed with full 360-degree coverage to guard against prying, hammering, and tampering, keeping your trailer safe - WEATHER-RESISTANT KEYHOLE – Integrated keyhole cover keeps dirt, debris, and corrosion at bay, ensuring smooth operation in all conditions - UNIVERSAL FIT & WARRANTY – Compatible with most coupler sizes and backed by a limited lifetime warranty for long-term security and peace of mind ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B084ZW5BNZ | | Batteries | 1 Unknown batteries required. | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 439,696 in Automotive ( See Top 100 in Automotive ) 4,660 in Trailer Couplings & Accessories | | Customer Reviews | 4.5 4.5 out of 5 stars (4,075) | | Date First Available | 1 Jan. 2024 | | Finish | Powder Coated | | Included Components | Lock, 2 keys | | Item Package Quantity | 1 | | Item Weight | 1.45 kg | | Item model number | UMAX50D | | Manufacturer | Trimax | | Material | Chrome Steel Aluminum | | Part Number | UMAX50D | | Product Dimensions | 24.77 x 23.5 x 10.16 cm; 1.45 kg | | Size | UMAX50D | | Style | UMAX | ## Images ![Trimax - UMAX 50D - Trailer Lock for Hitch, Dual Purpose Transforms to U Lock - Trailer Hitch Lock for 1-7/8" - 2-5/16" Couplers, All Coupler Types - Image 1](https://m.media-amazon.com/images/I/81oaNty4dDL.jpg) ![Trimax - UMAX 50D - Trailer Lock for Hitch, Dual Purpose Transforms to U Lock - Trailer Hitch Lock for 1-7/8" - 2-5/16" Couplers, All Coupler Types - Image 2](https://m.media-amazon.com/images/I/81qhq9-2dQL.jpg) ![Trimax - UMAX 50D - Trailer Lock for Hitch, Dual Purpose Transforms to U Lock - Trailer Hitch Lock for 1-7/8" - 2-5/16" Couplers, All Coupler Types - Image 3](https://m.media-amazon.com/images/I/81mtR+V0JDL.jpg) ![Trimax - UMAX 50D - Trailer Lock for Hitch, Dual Purpose Transforms to U Lock - Trailer Hitch Lock for 1-7/8" - 2-5/16" Couplers, All Coupler Types - Image 4](https://m.media-amazon.com/images/I/81rGyfs1wdL.jpg) ![Trimax - UMAX 50D - Trailer Lock for Hitch, Dual Purpose Transforms to U Lock - Trailer Hitch Lock for 1-7/8" - 2-5/16" Couplers, All Coupler Types - Image 5](https://m.media-amazon.com/images/I/71jJ3AbWWoL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by B***S on 10 April 2019* Hardened steel shafts wouldn't be easy to cut, and a thief would need to cut both shafts to remove the device from the hitch.
