ICEPIDER by e-climb.com. Protection device to place in holes left by the ice axe pick. High strength due to a very low point of pull, there isn't hardly any leverage. Easy to extract using the ice pick as leverage. There's a notch to facilitate extraction from above once the hard move has been dealt with. Very useful when it is difficult to place protections. Made of Chromoly steel. Can be introduced up to 6.5 cm into the ice.
