I have these hanging from the ceiling rafters of my basement to create an overhang-like climbing wall. I've purchased a variety of the screw on system jugs for the rafters given their ease of installation. These deep and rounded jugs were purchased with my wife and 7 year old son in mind, who are both newer to climbing and appreciate deep jugs with comfortable texture when climbing on our roof. I like to use these to take active breaks during an endurance climb, and also to facilitate directional changes when I'm climbing in a circular route on the roof.
