If you have any of the HI-Lift components on your vehicle such as the Jack Mounting Kit, then you can secure your jack with the Hi-Lift Versatile Locking Knob. The Locking Knob has been designed to replace the existing knob found on the mounting kit, to be able to be locked with the supplied key. Once locked, the knob will turn, however it cannot be removed. 

This is a preferred component that can be used on Hi-Lift’s adjustable tube-mounts, as well as the Loc-Rac. It may also be used to secure the Winch-Clamp Spreader Attachment found on the Hi-Lift X-Treme Jack models.
