Our story began with a family trailer being stolen with thousands of dollars of

equipment inside. We decided to develop strong, durable locks to ensure that wouldn’t happen again to anyone.

How did we get our start?

• HEAVY-DUTY PUCK LOCKS: It’s important to do everything you can to protect your belongings and your trailer from being stolen. Our strong and pick-resistant puck locks help keep your rear and side enclosed trailer doors secure.
• TOUGH PUCK LOCKS: These padlock cylinders are constructed from aircraft-grade 6061 solid aluminum, so they’re resistant to picking and corrosion. Each lock features a hidden and fully shielded shackle that protects against bolt cutters and prying tools.
• UNIQUE KEY DESIGN: Our puck locks have a special key design that prevents lockpicking and deters would-be thieves from making a copy of your lock keys. Each lock comes with 2 keys, and all keys are keyed alike for your convenience.
• LOCK DIMENSIONS & SIZES: Each puck lock has a large opening on the back to accommodate for swivel hasps on an enclosed trailer door. The shackle opening measures 1 3/4" L x 1 3/4" W x 7/8" H and has a depth of 1 1/4".
• PROVEN INDUSTRIES: We are dedicated to providing our customers with the most effective trailer locks on the market. We carefully research and manufacture our locking systems from conception to fabrication in the USA.
