Here is a pic of mine. They have a stainless carabiner at the top end that feeds through a hole in the aluminum angle running along the roof crossbars. At the lower end, there is another stainless carabiner that runs through one eye of a turnbuckle. The other eye of the turnbuckle is attached via stainless carabiner to a u-bolt that's attached to the brushguard. When not in use, I loosen the turnbuckle, detach from top then bottom, roll 'em up and store in the front door pockets.

The aluminum rails up top are 1.25" x 1.25" x .25" and work great for taking the limbs off of the risers and letting them ride all the way to the back above the crossbars. They also work great as anchors for tying stuff to the roof and handles to grab when standing on the steps.
