Frequently Asked Questions

AI
Yes. Most locks are designed for specific coupler diameters (1-7/8, 2, or 2-5/16 inches). Universal models adjust to fit multiple sizes, but you must verify compatibility with your trailer's tongue to ensure a snug, secure fit that prevents tampering.
Critical. Since these locks remain exposed to rain, snow, and road salt, look for models with rust-resistant coatings or stainless steel components. Poor weather resistance can lead to jammed mechanisms, leaving you unable to unlock your trailer when needed.
Keyed locks provide a good baseline of security by preventing casual theft. However, for high-risk areas, consider heavy-duty, reinforced steel options with pick-resistant cores. Some premium models offer additional features like locking pins or reinforced shrouds for enhanced protection.
