FedEx delivered my package today but as I picked up the 3'+ long box the contents came sliding out the other end with no tape popped open! The straight edge was loose from its hard case because the sliding keeper was loose as the screw's threads are stripped. No damaged areas on the box at all so I don't know how the screw threads got stripped.
Luckily the box was positioned with the straight edge on top or it could have hit the concrete or worse yet the four bricks high wall above the concrete surface! Dumb luck had it was windy, I was holding on to my storm door with one hand or I might have spun around and it could have been much worse.
There doesn't appear to be any damage on the straight edge itself that I can see right now but who knows when/where else it came sliding out while in route.
