Frequently Asked Questions
Will this lock fit all 2″ trailer couplers?
Yes, it is designed to be a universal fit. The ball-shaped insert is engineered to work with standard 1-7/8″, 2″, and 2-5/16″ coupler sockets, and the adjustable ratchet mechanism ensures a secure fit on almost all straight tongue and A-frame trailer couplers.
Is the lock weather resistant?
Absolutely. The lock body is made of high-strength die-cast aluminum with a premium, high-visibility yellow powder-coat finish, while the steel shackle is treated for maximum corrosion and rust resistance, making it ideal for long-term outdoor use in harsh weather conditions.

Yes. Contact us with your key code for replacement key support.
