Expedition Master III
Some accessories come with a standard bolt and nut secure arrangement, while a few come with the "LOOPED" spring secure pin arrangement. I replaced my nut and bolt safety system for ease of use with each of them. They were cheap at the hardware store, and made tracking where that easy to lose nut was at all times unnecessary.In the picture you can see the chrome safety retainer bolt/nut. The safety spring retainer loops under the jacks step/foot and clips on the other side of the pin. I use them for the bumper lift, the wheel jack lift, along with the recovery unit attachment which is like the picture also.
