I needed a forklift part and wasn’t sure which one fit. They asked for the model and serial number, got back to me quickly, and made sure I ordered the right one. Really helpful.

Frequently Asked Questions

Q: How does this gooseneck trailer lock prevent theft? A: It slides over the gooseneck coupler and locks in place with the key, completely blocking the ball socket so a hitch cannot be connected or the trailer towed.

Q: Will this lock fit my trailer's coupler? A: It is designed for standard 2-5/16" ball gooseneck couplers and fits most RVs, livestock haulers, and utility trailers; measure your coupler opening before ordering to confirm fit.
