What is the stretched out size of these safes? I want to use it to protect a lot of gear carried on a bicycle trailer. This is an open trailer and without a cover or fitted box or bag for it. So we would prefer something that wrapped the whole way around but fit down into the trailer sides which are open too but do have metal tubes going around forming something of a box. Perfect to tie this safe to with carabiners. We might make our own lightweight waterproof nylon bag to keep things safe and out of site both. But will have awkward lengths of tent and sleeping mats. Some food items. Will have bike panniers on two other bikes which would be nice to put on the trailer for safe keeping when we are away from the bikes too. So what it actually stretches out to would be helpful. We could make do with it stretched out just to cover the top but would be nicer if it went all the way around. Our trailer is about 34-36 in length and 27 wide at the top of the slanted sides. A bit smaller at the bottom floor. What we put on it will determine the height.

While I was in New Zealand recently, I saw an excellant wire(?) mesh bag that went around the backpack, so that you could check your pack on the airplane and it would not get caught in the equipment. It encased the bag and locked. Anyone have any experience with something like this? Any idea where to get one? (Or what it is called?) Is it worth the money?

The smallest size the pacsafe comes in is 55, right? Well, I have a 48L hiking pack which I would consider locking with the pacsafe 55, but will the mesh protector still work with something smaller?
