At Proven Industries, we are dedicated to providing you with strong, effective, and secure products. Our family-owned business caters to customer needs without sacrificing quality, and our products are manufactured in the USA to ensure more control over development and delivery.

Each of our locks features a universal key system that fits our Hyper Hitches product line. Keep your possessions safe with our high-quality lock systems. Our story began with a family trailer being stolen with thousands of dollars of equipment inside. We decided to develop strong, durable locks to ensure that wouldn't happen again to anyone.

Each lock is constructed from hardened steel, which helps prevent burglars from using power tools, hammers, and crowbars on the device. Our custom-tailored locks mount only on specific couplers. Check the coupler sizes that are compatible with our lock hardware to ensure that your chosen lock matches your trailer coupler.

We pride ourselves on manufacturing our products in America! By doing so, we are able to ensure more control over the development and delivery of our products to our consumers. We don't have board members directing us to produce lower-quality products to increase the bottom line. This allows us to continue building incredible, effective, and secure products.

Our innovative key system features the ability to key all your locks alike for your convenience! It's important to protect your trailer from being stolen. Our puck locks keep your rear and side enclosed trailer doors secure.

These padlock cylinders are constructed from aircraft-grade 6061 solid aluminum, so they're resistant to picking and corrosion. Each lock features a hidden and fully shielded shackle that protects against bolt cutters and prying tools. Our puck locks have a special key design that prevents lockpicking and deters would-be thieves from making a copy of your lock keys. Each lock comes with 2 keys, and all keys are keyed alike for your convenience.

Each puck lock has a large opening on the back to accommodate for swivel hasps on an enclosed trailer door. The shackle opening measures 1 3/4" L x 1 3/4" W x 7/8" H and has a depth of 1 1/4". We are dedicated to providing our customers with the most effective trailer locks on the market. We carefully research and manufacture our locking systems from conception to fabrication in the USA.
