I use bungee cords to attach things to them. I use my truck as a truck so I’m always in need of places to attach tools and other items. These are very well secured but when I use them to tie down heavy items I use the lowest holes of the Molle and haven’t had any problems.
I ordered mine and they came pretty quickly. I have a direct contact there and I just sent him a screenshot of your message. I’ll let you know when he responds.
