Description
Product Overview
Protect your valuable trailer investment with the iFJF 5th Wheel King Pin Lock. Constructed from solid steel with a bright safety-orange finish, this heavy-duty anti-theft device prevents unauthorized coupling to your trailer's king pin — the #1 target for trailer thieves. Whether you're securing an RV, semi-trailer, container chassis, or camper, this lock provides visible, effective theft deterrence.
Trailer theft is a multi-billion dollar problem in North America. A professional thief can hook up and drive away with an unsecured trailer in under 60 seconds. This king pin lock physically blocks the fifth wheel coupling mechanism, making it impossible to connect without removing the lock — and the included high-visibility warning tag serves as a powerful psychological deterrent.
