"Please delete this sentence; however, now we need to address the issue of “anti-traction” devices or anchors, i.e., devices designed to hold you firmly in one place. Anchors cannot
use metal in contact with the carpet to “stay put.” Similarly, metal traction or anchor surfaces are not allowed on the ramp surfaces."

I believe the spirit of the rule is to prevent teams from using something metal to dig into the playing field, and anchor themselves onto the top of the ramp. They specifically say "anchors cannot use metal in contact with the carpet to "stay put"." So, anchors that are not made with metal, such as a plastic suction cup should be allowed, as long as they do not damage the playing field.
