It was all floppy and I cannot clamp the bottom because I did not cut it. I I drove a stake inside the door and used that to hold the bottom 2x4, clamped the top, screwed the 2x4s to the coroplast, and then drove almost 6" screws from the sides, although none of it was straight.
Um...
Hey guys?
Now what do I do?!
I need to install a door handle and then what?!
