Review on 🔒 Ultra-Fab Products 21-001090 Super Grip Chock - Secure Wheel Locking Device (1 Pack) by Gabe Evans

There was a set on a pre-trip trailer so I bought it again for my fifth wheel. Liked the first experience. Finally get on your way, and one of them is a beast that needs to be deployed. I assume something is wrong with the thread, I literally have to lay it on its side, stand on it to keep it still and then press the button with my other foot. He fights back. That is hard. It's been like this since day one. Anyone have any ideas?
