About Us

When Madco Motorsports' prized race car trailer was stolen right out of their compound, the road map was drawn.

After a disappointing search of existing locks available on the market, the team took the resources of their own innovative machine shop and designed a coupler lock that makes trailer owners feel they have the best lock available to keep their possessions safe. 

When it was apparent Madlock was a superior design, a patent was filed and granded (US Pat. 11667164B2) 

Sales and consumer demands have called for Madlock Trailer Locks LLC to create a company that can continue to supply the demand for TV dealers and consumers across the US and Canada. Madlock is currently manufactured in the USA/Canada with the objective of creating more local jobs close to home and keeping quality standards at the highest level.
