Steve:
We visited a booth at last Fall's Overland Expo (in North Carolina) selling industrial and military-grade rubber fasteners, holders and securing straps of every conceivable size and shape. These things were used to secure items in/on/under helocopters, jets, MDTs, ambulences and expedition vehicles. We bought a huge quantity of items from them; I'll be installing some of these holders in our camper this summer. The rubber had stainless steel inserts embedded in them as reinforcement, for direct fastening to a roof, truck, boat, etc.
I'm looking for their catalog, and will get back to you on their Web contact info...
Cheers,
S-
