(888) 312-8812 Login SignupSecurity is the only thing that matters when you drop a trailer in an unsecured yard, and the JOST Fifth Wheel Trailer Hitch King Pin Lock is built to stand up to heavy-duty theft attempts. This JOST SK71022-02 lock is forged from high-strength steel to resist drilling, sawing, and prying, making it nearly impossible for an unauthorized tractor to hook up to your load. The design wraps completely around the kingpin, leaving no room for bolt cutters to get a grip. JOST uses a high-security key cylinder that is specifically treated to prevent seizing or freezing in winter weather, so you aren't stuck struggling with your own lock when it’s time to hook up and head out.
