The screws which hold my Cardinal cargo door latch pulled out years ago on my trailer. I replaced with larger screws and they just pulled out again.
For several years, I have been propping the door up with a 6ft long piece of 3/4 pvc pipe. The pipe has a short T fitting near one end. The T fits nicely on the edge of the door and the other end has a 1" rubber end cap.
I also use my stick for walking and moving things without me having to bend over. I can snatch several chalks from my wheels before you can get in your truck. I don't even have to bend over.
My grandsons think the stick is better to play with than the toys they bring along.
