I was thinking about mounting a downrigger bracket to the lid of the BlackPak but the bungee system makes it too loose for this. I picked up a couple of Poly hinges from US Plastics for under $5 that have the same size holes as the original yakattack screws. I used the existing corner support screw holes and drilled a couple more. I used stainless 1/4" machine screws and locks nuts. I'm pleased overall as I like things to open solid and close solid. It's just me... With the downrigger facing the opening side of the lid the hinges are plenty strong enough. Next I need to find a poly clasp.
