First, I pull it up once I am up and situated...I have 2 small packs on my treestand, my Thermacell with extra pads and fuel is in one..In the other I have my strap to attach me to the tree, some extra pins for my stand and 3 extra folding screws, they are about an inch and a half long and 3/4 inch in diameter...Once I pull my backpack up, it hangs on one of them...
I don't climb with extra stuff hanging on my climber, it affects the balance and to me that could be not safe...Also, anything hanging on the stand once situated is just in the way and something else to hit, swing and bring attention to you...
