I couldn’t be more impressed with this trailer lock. From the moment I took it out of the box, it was clear this is a serious piece of hardware. The heft and solid construction give me peace of mind. And the customer support I've received from Proven Industries has been amazing -- despite my best efforts I managed to purchase the wrong size, and the customer support team has been responsive and incredibly helpful!Bottom line: this lock is worth every penny.
