This opens up innumerable placement options by allowing the Curve Hex to slide past nubbins and irregularities that would block a traditional, straight-sided hex. The curves also allow C.H.s to cam into position by rotating on the convex face and setting up super-stable, 3-point contact with the concave side. Each piece offers four different placement options yielding a range that is similar to a camming unit of comparable size.Features: The classic hex design improved by adding curved faces 4 placement options The range of a cam at a fraction of the price and weight Color coded tubing makes identification easy Extruded 6061 - T6 Aluminum Pre-packaged set of all 10 Curve Hexes Recyclable packaging Includes comprehensive instructions on use, care and maintenance Size 1: Dimensions: .42 - .61in.
