Abstract
A polygonal mountaineering chock with at least two sets of opposed faces in which extensions of each set of faces defines an acute angle, and the median distances between the two sets of opposed faces are unequal, whereby the chock can be received in holding position in cracks or openings of two different widths. A series of such chocks in graduated sizes is provided, with the distances between the sets of opposed faces being uniformly increased, such that at least one position of one chock of the series will fit into any crack of a width between the smaller end of the narrower set of faces of the smallest chock and the larger end of the wider set of faces of the largest chock.
