Hooks attach inside wall to Fiamma case (truck side), inside wall provides extra privacy as well wind protection. Hooks have grommets which allow the mounting of lights or just about anything.

Shown here during enclosure mounting, the 7mm channel in the Fiamma allows the use of this "rope" for mounting and a completely sealed front edge.
