Experimenting with different the down points for securing my fridge freeze. The more I putz with them, I think they might be good for other areas where I use ratchet or trucker bungees to secure stuff in the truck. These are made with 1" bar stock, nails and bugger welds.
To do that you would just make the nail a V shape to allow for the hook to go into it. Also, there will be a hole to allow the thing-ma-jig to be bolted down.
