Wondering how we started? It all began with the unfortunate theft of a family trailer containing valuable equipment. Determined to prevent such incidents from happening again, we set out to create durable and sturdy locks that can withstand any attempted break-ins.

Made from hardened steel, our locks are built to resist power tools, hammers, and crowbars used by burglars. Each lock is custom-tailored to fit specific couplers, so make sure to check compatibility with your trailer coupler before making a selection.

Our pride lies in producing all our products in the USA, giving us the ability to maintain high standards of quality and timely delivery to our customers. As a family-owned business, we have the freedom to focus on creating exceptional and secure products without compromising on integrity.

Keyed alike for convenience, our innovative key system allows you to manage multiple locks with just one key. Protect your trailers with our heavy-duty puck lock, designed to keep your rear and side enclosed trailer doors securely locked.
