Madlock was developed from the need to provide the highest level of security for stamped steel trailer couplers.  The story behind the creation of the product serves as an example of why racers should do whatever it takes to protect their investment.


After returning home from a successful racing event in Las Vegas, the Madco Motorsports team found themselves victim to an unfortunate trailer theft which was thought to be secure behind their shop having been equipped with a generic trailer lock. The Madco Machine team recognized the need to provide the market with a more secure, superior method of protecting trailers and the content inside of them.


A lock needs to be built for the purpose it is designed – to protect and deter the unlawful appropriation of equipment, be that recreational in nature or other usages common to trailer owners today. Protecting our belongings has become paramount in today’s world where theft has become commonplace. Most locks on the market today simply do not deliver the high-level security that a trailer owner requires.


That is why the crew at Madco Machine engineered a design for a top-quality lock that is smart, built for the job and user friendly. Madlock Trailer Security (patent pending) is now one of finest locks & the smartest choices on the market today. Madlock is built in house at the Madco Machine manufacturing facility where they guarantee top quality & assure its longevity.
