VEVOR Trailer Hitch Lock Kit, Fits for 1-7/8 in, 2 in, 2-5/16 in Couplers, Heavy-Duty Anti-Theft Trailer Ball Lock with Keys, Prying-Resistant, Adjustable Height Design for RVs, Boats, Trailers

Universal 3-Size Compatibility Fits 1-7/8″, 2″, and 2-5/16″ Couplers

The VEVOR coupler hitch lock features a universal design that works with the three most popular coupler sizes: 1-7/8 inches, 2 inches, and 2-5/16 inches. This means you do not need different locks for each trailer, RV, or boat. Approximately 95% of standard trailer couplers found on utility and leisure trailers are compatible with this lock. The precise engineering of the fit ensures there are no gaps or movements that could compromise security.

The mechanism can be adjusted to accommodate couplers with slight manufacturing variations, while still maintaining the tight fit needed to deter thieves. As it works with all kinds of devices, the lock is ideal for fleets and rental companies.

Heavy-Duty Aluminum Alloy Construction with Zinc Anti-Pry Core

The excellent strength-to-weight ratio of the aluminum alloy body makes it resistant to rust and damage from theft attempts or exposure to the elements. The 2.87-pound weight gives a solid feel and safety without putting too much weight on the trailer tongue. The hardened construction and geometric shape of the zinc alloy core make it very difficult to pry.

The two-material construction combines the anti-corrosion properties of aluminum with the greater hardness and anti-tampering properties of zinc. This method of construction creates a lock body that remains structurally sound even under heavy stress, and the internal mechanisms prevent thieves from picking, drilling, or prying.

Advanced Chrome Plating with Powder Coating for All-Weather Durability

The multi-layer finish method starts with chrome plating, which protects against corrosion. Next comes powder coating, which protects against impact and UV light. This mix can handle changes in temperature, salt exposure, moisture, and UV radiation without losing its security function. The finish looks good and works well, even after years of exposure to the elements.

Powder coating forms a molecular bond with the chrome surface, preventing chipping, flaking, or peeling like painted finishes do. Because it is so strong, the lock will continue to function as a security system and look professional for a long time, even in harsh winter conditions or marine environments.

Tool-Free Operation with Precision-Machined Anti-Jam Lock Core

You do not need any tools to install or use it, so you can set it up quickly anywhere without carrying extra gear. Put the lock body into the coupler, use the height device to position it correctly, then use the key to lock it in place. The precisely polished lock core prevents the mechanism from getting stuck and ensures it works smoothly even after prolonged exposure to the elements.

Drainage channels and corrosion-resistant materials in the anti-jam mechanism prevent ice, dirt, and moisture from impeding the lock’s operation. With this level of dependability, the coupler hitch lock will always work correctly when needed most. You will not have to deal with frustratingly stuck or frozen locks in critical security situations.

Professional 11-Position Height Adjustment System for Optimal Coupler Hitch Lock Fit

The 11-position height adjustment system works with a variety of trailer tongue shapes and coupler mounting arrangements. Regardless of the coupler maker, trailer age, or mounting variations, this adjustment range ensures the lock is in the right place. This way, no one can accidentally shift its position while moving or storing the trailer.

The adjustment mechanism lets you move the coupler hitch lock incrementally, improving safety by closing gaps between the coupler and the surrounding hardware. This exact fit prevents leverage strikes and ensures the lock does not interfere with normal use or storage of the trailer. You can use normal ball mounts, adjustable mounts, and special hitching gear with this system.

Complete Coupler Hitch Lock Security Package with Padlock and Locking Pin Protection

The full security system includes the main lock body, a weatherproof padlock, and a locking pin that protects against theft in multiple ways. The locking pin keeps the front mechanism in place, and the padlock keeps the main mechanism safe. This dual-locking system makes it very hard for thieves to get in, as they have to overcome more than one security feature.

The parts that come with it work together to make overlapping security zones that protect against different types of attacks. The package comes with two keys for easy use and backup access. You do not have to worry about losing keys while traveling or storing them for a long time.

Multi-Vehicle Applications for Trailers, RVs, Boats, and Off-Road Equipment

The design is flexible enough to fit utility trailers, travel trailers, boat trailers, RVs, off-road vehicle haulers, and equipment trailers for use in homes, businesses, and leisure areas. The universal coupler compatibility and adjustable height system work with a wide range of tow vehicle types and tongue configurations without any modifications.

The robust construction meets the security needs of boats, bikes, ATVs, construction equipment, and recreational vehicles, all of which are high value assets. Professional looks and steady operation make it suitable for commercial fleets, rental businesses, and personal use, where consistent security is required.

Compact 7.6″ x 5.51″ x 2.76″ Design for Easy Storage and Transport

The 7.6″ x 5.51″ x 2.76″ overall dimensions make it easy to store in toolboxes, glove compartments, or trailer storage areas without taking up too much room. Although it weighs only 2.87 pounds, its weight provides stability while still making it easy to install and remove. The small size makes it easier to store or move in service vehicles when not in use.

The thoughtful proportions strike a balance between security performance and ease of handling. The lock fits easily into normal toolboxes and is strong enough to successfully deter theft. This smaller design makes the lock useful for people who need portable security or who frequently change their settings.
