A what!? :-) I made these hooks to mount biclycle luggage straps to the table of my camper van. This way, you can easily fix any loose stuff to the table when driving. The chances are small that you can find the exact same luggage straps i have, but these hooks should be ok for other straps, as long as you can fit a M4 bolt through the end caps (i have drilled a 4mm hole in order to do so) The hooks are made for a 18mm thick table top, but it can be used for anything between 12mm and 18mm when you remove some material with a hack saw.
