Disclosed is a security device to prevent trailer theft that attaches to the lug thread of a wheel hub to prevent wheel rotation or wheel mounting. The device includes an outer cylinder, an inner cylinder, a locking lug nut that screws onto the lug thread, and a lug nut key. The outer and inner cylinders rotate around and extend beyond the locking lug nut, utilizing a design that defeats many common methods for removing wheel locks, or requires specific tools that create considerable noise and time to defeat. An optional security bar can be engaged by removing two lug nuts to prevent wheel rotation. Also disclosed is an embodiment that prevents wheel installation on a bare wheel hub. |
