10 Best Gooseneck Hitch Locks 2026 in the United States

This Ft. Knox Gooseneck Round Tube Coupler/Hitch Trailer Lock Combo is a solid choice if you need strong protection for round tube gooseneck couplers. Made from 3/16" cold rolled welded steel, it’s built tough against common theft methods like hammering, bolt cutters, and crowbars.

The bright yellow powder coat finish not only protects the metal from weather but also acts as a visual deterrent to thieves.

It’s designed specifically for round tube gooseneck couplers, so it’s very important to measure your tube size beforehand as this lock won’t fit square tubes. While it’s heavy at 32 pounds, indicating solid construction, this might make it a bit less convenient to handle or store for some users. The locking mechanism is straightforward, but because it’s a heavy-duty security lock, it may take a little more effort to install compared to simpler locks.

Weather resistance is well covered thanks to the powder coating and rugged steel, so it should hold up well outdoors.
