Madlock's patent pending one piece design makes a user friendly lock which is quick & easy to use for most members of the family or employees. Madock simply slides over the coupler flange lip, then the pin body is lifted into position. With the key inserted the lock shackle is pushed in & rotated to lock position. Your trailer is now secure!
