Muddy Box Blind Bow Hanger

No instructions to install in hollow plastic roof on Muddy blinds. The expanding element that has to be installed exactly correct is very flimsy and is broken at the least twist of the tightening disc. Ruins the device in the first few seconds you attempt to install in the blind pre-fab hole locations. I was lucky and able to use a screwdriver to gently pry the expanding elements out to get it started expanding and then able to very carefully hold all parts of the hanger while twisting the tightening ring to further expand the device in the hole. I am fearful it might fall out and bow or gun free gall to the ground. This is a needed idea, and the only device that I have found to install a bow or gun hanger in a Muddy blind. They need to replace the flimsy expanding metal part with a tougher more durable expanding element. needs instructions - perhaps there is utube installation video which would be critical to review prior to attempting installation
