The Black Diamond Pecker climbing tools are ideal for clean aid when climbing buildings. Their small size allows them to be placed or hammered into mortar lines, window frame recesses and other thin lines of weakness. Peckers can be hand-set and cleaned quickly when quietness is required. When micro nailing, their double tapered thin, serrated blades hold solid - especially in softer rock. A new swaged cable, lifts out the way when pounding the eyes during removal. The largest size also works well in the mixed medium, offering additional options on mixed lines when small cracks or frozen turf are natures only offerings.
