Product Details
Best Review
Customers find the trailer lock to be a great theft deterrent that works well and is easy to install, taking just one minute to attach. The sturdy steel construction resists tampering by thieves, and its bright red color warns potential thieves from a distance. While the lock fits multiple tongue sizes, some customers report it being rather loose. The key functionality receives mixed reviews, with several customers reporting issues where the key won't turn the mechanism.AI Generated from the text of customer reviews
