Thanks for looking into it, Ken. What’s your plan now? Are you going to ask CLC to swap out the 20# for 30 or order them on your own and compare? Looks like they are going for around $30 a set (assuming ATT-SL34305 from https://www.jamestowndistributors.com/userportal/show_product.do?pid=11963 are the right model).
I definitely see the issue with the heavier hasp @szerby mentioned but I’m also concerned about the 30# pistons putting extra strain on the hinges and possibly lifting the hatch off the gutter gasket.
