Archie - Warren, MI

I've been in business 3 years, and had 3 trailers stolen. I bought a Mean Dog for every 2 bolt trailer, and  I haven't had a trailer stolen since. I can finally sleep at night knowing my trailers aren't going anywhere.

Purchasing the Mean Dog lock was a very smart move to protect my dumpsters and trailer investments. I highly recommend the Mean Dog Lock

The Mean Dog Lock is the most secure lock out there. I use them on all my trailers. Very well-built and efficient. I can sleep a lot better now, knowing the Mean Dog is on the job protecting my equipment.
