Infinite Rule Security

<h3>About Infinite Rule Security</h3><p>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. <strong>Necessity being the mother of invention</strong>, 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.</p><p><a href="/14683-infinite-rule-security-trailer-hitch-lock-14537">Trailer hitch locks</a> 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.</p><p>One of Infinite Rule Security's most valued selling points is their <strong>keyed-alike system</strong>. 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.</p><p>Beyond receiver locks, Infinite Rule Security produces a comprehensive range of <a href="/14683-infinite-rule-security-trailer-hitch-pin-19997">trailer hitch pins</a> available in multiple diameters — including 1/2&quot;, 5/8&quot;, and 3/4&quot; — with application-specific fitment engineered to match popular hitch brands like B&amp;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.</p><p>Infinite Rule Security also extends its protection to off-road accessories with <a href="/14683-infinite-rule-security-shackles-202507">shackle locks</a> 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.</p><p>As a small, family-owned American business, Infinite Rule Security manufactures, ships, and services every product domestically. The company holds <strong>three design patents</strong> 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.</p><ul><li>100% made in the USA — manufactured, shipped, and serviced domestically</li><li>Third-party tested for strength and anti-theft performance</li><li>Keyed-alike system across multi-lock orders</li><li>Weatherproof rubber caps and O-rings for all-weather reliability</li><li>Application-specific fitment for leading hitch brands</li><li>Three design patents and SEMA award recognition</li></ul>

Product Details

The Infinite Rule Security 61801-S is a 3-piece keyed-alike hitch lock set custom-engineered for the CURT 2.5-inch Adjustable Channel Mount 20,000 lb hitch (models #45951 and #45955). This mixed pack includes locks for the hitch itself plus an additional lock for the 2.5-inch receiver, delivering comprehensive protection for your entire towing setup in a single purchase.

Each lock is precision-machined from premium stainless steel and features a patented threaded locking system with a head-over-pin design. The locks are rigorously third-party tested to a 21,000 lb heavy-duty rating, giving you confidence against attempts to break, cut, or pick them.

Key Features:

  • Application-specific fit — designed exclusively for the CURT 2.5-inch Adjustable Channel Mount 20K LB hitch
  • 3-piece mixed pack — includes hitch channel locks plus one 2.5-inch receiver lock for full towing system security
  • Keyed alike — all locks in the set operate with the same key for convenient, one-key access
  • Two keys included — carry one, store one as a spare
  • Machined stainless steel construction — resists rust and corrosion for long-term durability
  • Weatherproof rubber cap and O-ring — seals out rain, dirt, road grime, and debris to keep the locking mechanism operating smoothly
  • Patented threaded lock system — head-over-pin design for maximum security and tamper resistance
  • 100% Made in the USA — manufactured, shipped, and serviced domestically at InfiniteRule's family-owned facility in Oxnard, California

The 61801-S is compatible with CURT 20K Channel Mount Adjustable Hitch models with a 2.5-inch shank. All locks ship keyed alike within the set, and InfiniteRule can key future lock purchases to match existing sets by contacting their customer service team.

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!
