Infinite Rule Security

<h3>About Infinite Rule Security</h3><p>Infinite Rule Security was born out of a real-world problem. <strong>Founded in 2012</strong> by Brad Mateko, the company got its start when Mateko couldn't find a quality lock to protect the off-road hooks on his own vehicle — so he built one himself. What began as a personal solution quickly evolved into an award-winning line of precision-engineered locking pins trusted by towers, off-roaders, and outdoor enthusiasts across the country.</p><p>From the very beginning, the mission has been straightforward: produce the strongest, safest, and best-looking locking pins on the market. Every product in the InfiniteRule lineup is <strong>100% manufactured in the USA</strong>, machined from premium stainless steel, and third-party tested for superior strength. The brand 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) in 2015 — a testament to the innovation baked into every pin.</p><h3>What Makes InfiniteRule Different</h3><p>The core of InfiniteRule&apos;s appeal is a system that towers have long needed: <strong>keyed-alike locking pins</strong>. Whether you&apos;re securing a receiver, a ball mount, a shackle, or an off-road hook, all your InfiniteRule locks can share a single key. That means one key for your entire towing setup — a small detail that makes a big difference on the road or trail.</p><p>Every pin features a patented threaded lock system and a head-over-pin design that resists cutting, picking, and brute-force attacks. Weatherproof rubber caps with O-rings seal out dirt, water, and road grime, keeping the mechanisms operating smoothly for years. Locks are tested to heavy-duty ratings — many up to 21,000 lbs — so they stand up to the demands of serious towing.</p><h3>The InfiniteRule Product Lineup</h3><p>InfiniteRule&apos;s catalog is purpose-built around towing and trailer security. Their flagship <a href="/14683-infinite-rule-security-trailer-hitch-lock-14537">trailer hitch locks</a> are custom-engineered to fit specific receiver sizes and hitch brands, including B&amp;W, Gen-Y, Shocker, and Rhino Hitch, among others. For those who need to lock down their ball mount or coupler hardware, the brand&apos;s <a href="/200290-coupler-ball-mount-locks-infinite-rule-security-14683">coupler and ball mount locks</a> provide the same precision fit and anti-theft engineering in a package designed for adjustable and fixed ball mounts.</p><p>Protecting the coupler connection itself is equally important, and InfiniteRule&apos;s <a href="/19998-trailer-hitch-coupler-infinite-rule-security-14683">trailer hitch couplers</a> and coupler locks are designed to prevent unauthorized hitching of your trailer when it&apos;s parked and unattended. Rounding out the lineup, the brand offers a variety of <a href="/14683-infinite-rule-security-trailer-hitch-pin-19997">trailer hitch pins</a> — both locking and non-locking — to suit a wide range of receiver classes, as well as an assortment of <a href="/201094-trailer-parts-accessories-infinite-rule-security-14683">trailer parts and accessories</a> that complement any towing setup.</p><h3>Built for Towers, Off-Roaders, and Everyone In Between</h3><p>What sets InfiniteRule Security apart in a crowded market is the combination of custom fit, domestic manufacturing, and a genuine commitment to quality at every step. Each pin is individually inspected before it leaves the facility, and the brand manufactures, ships, and services all products from within the United States. For anyone who has invested in quality towing equipment, InfiniteRule offers the peace of mind that their gear will still be there when they return.</p>

Good experience!

Shopping at checkout was really easy, but I haven't installed the product yet so I can't give a proper review

Extremely fast shipping,safe and proper packaging. happy to get the last one available in the U.S .hope it preforms as advertised.

A dealership broke one of the parts of a rim I have on a car and needed a part in a pinch! Price was great and shipping was incredibly fast! Really happy with the selection and listing such a specific part, other sites just listed part numbers without pictures so THmotorsports made it easy to trust.

Great price, quick shipping.

Great Website!
