Midwest pet cages are designed to be easy to put together—the parts come assembled, so the crate just needs to be set up. You begin with the pan at the bottom of the crate facing down. For most crates, you then need to unlatch the lock on the outside.
Next, lift up the top and put it to the side like you’re opening a book. Now lift the top upward, which will also erect two of the sides. Pick up one of the remaining two sides from inside the crate and connect it to the other two sides. The final side can now be lifted and secured in place. Reverse the project to fold down the crate for easy storage.
