The Jarbidge comes with one carabiner at each end. I just added one carabiner to each end and attach them to the am steel at each corner. The first 2 pics are with the hammock flipped bottom-up. The third pic is right side up. Each corner is the same. Even though it doesn't seem to need it ( can't really test yet since this summer heat never ends) I like the idea of a shock cord going across the ridge line (in the case of the Ridgerunner, the bug net).
Edit: decided to quick rig a center cord across the bug net. I don't know if it's really needed but it does hold the quilt in snugly.
