All gooseneck coupler locks are specially designed to secure your gooseneck trailer from theft or unauthorized towing with a glove-like fit to your coupler. The lock components are interlocked, eliminating loose parts that require assembly each time you install or remove the lock from the coupler. This feature makes installing and removing the lock quick and easy. Accessible design with easy-access one-hand operation – making installation and removal on the coupler or storage bracket a breeze.
