Last year I made some adjustable locking straps to keep jerry cans secure, I posted about them earlier in this thread. I made them out of standard "removable link" agricultural chain to provide for lots of adjustment and security. Here's a few photos of them:
They've got a big adjustment range by adding/removing links, and a fine adjustment range in the latch to snug the can down very tightly. As shown in the photos above they can be used with multiple types of cans, and with jerry cans the swivels at the ends allow the strap to go over the cap to prevent it from being opened when the strap is in place. I also made up covers for the chain so they don't scratch the cans.
The straps have worked out really well, although the agricultural chain I used wouldn't make sense if some company were to pick this up as a production product because the links are too tight to remove without a tool unless each link is modified slightly. To eliminate the ag chain issue, I've designed a new style of link that can easily be added/removed. I sent CAD drawings of the link parts to a friend at a company that's got lots of laser capacity; today this pile of parts arrived:
I'll assemble these parts into some straps for testing in the next few days.
