About Infinite Rule Security
Infinite Rule Security was born out of a real-world problem. In 2012, company founder Brad Mateko went looking for a way to secure the off-road hooks on his own vehicle and found that no adequate product existed on the market. Necessity being the mother of invention, he set out to engineer a solution himself — and what started as a personal project became an award-winning line of locking pins and security hardware trusted by towing enthusiasts across the country.
Trailer hitch locks sit at the heart of the Infinite Rule Security catalog. The company's machined stainless-steel locking pins are rigorously third-party tested for superior strength and rated up to 21,000 lbs, making them a serious choice for drivers who tow heavy loads. Every lock is built with multiple anti-theft features, including an innovative internal turn-key locking mechanism that resists picking, cutting, and brute-force attacks.
One of Infinite Rule Security's most valued selling points is their keyed-alike system. Customers who order multiple locks in a single order receive units that all operate on the same key — a huge convenience for anyone managing a truck, ball mount, and trailer coupler simultaneously. Combined with tight-fitting weatherproof rubber caps and O-rings that seal out dirt, water, and debris, these locks are built to perform reliably in all conditions.
Beyond receiver locks, Infinite Rule Security produces a comprehensive range of trailer hitch pins available in multiple diameters — including 1/2", 5/8", and 3/4" — with application-specific fitment engineered to match popular hitch brands like B&W, GEN-Y, Rhino Hitch, and others. This precision-fit philosophy means a lock that doesn't rattle, doesn't slip, and actually deters theft instead of just giving the appearance of security.
Infinite Rule Security also extends its protection to off-road accessories with shackle locks and locking pins for D-rings, hooks, and recovery gear. Whether you're securing a recovery shackle on a trail rig or locking down towing hardware on a work truck, the product lineup covers the full spectrum of towing and off-road attachment points.
As a small, family-owned American business, Infinite Rule Security manufactures, ships, and services every product domestically. The company holds three design patents and earned first runner-up honors in the Best New Van/Pickup/Sport Utility Vehicle Product category from the Specialty Equipment Market Association (SEMA). For drivers who take their equipment seriously, Infinite Rule Security represents a level of craftsmanship and accountability that's increasingly rare in the security hardware space.
