Protect your trailer with a Bolt lock
Bolt Coupler Lock Courtesy Bolt

The Bolt trailer coupler lock deters theft of unattended trailer boats with hardened steel construction that prevents hitching the trailer to a vehicle. It’s powder-coated for corrosion resistance, and the adaptable design fits trailers with 1 7/8-, 2- and 2 5/16-inch couplers. It is engineered to work with the patented, weatherproof Bolt lock (included) that can be easily matched to your vehicle’s ignition key. It features a double ball bearing and a plate tumbler side bar to prevent picking the lock. $69.99; etrailer.com
