Concrete – internal rotating metal rod
*Assistance* I'm trying to make a DIY woodcrete nest box (for birds and bats) and I can't find any information on how to install a rotating bolt or metal rod to hold the front of the box in place (see photo for example). Please let me know your thoughts on how to carry this task out.
